How to Annoy Your Sister

Last Updated: January 5, 2023

Let's face it: sisters can be super annoying, so sometimes it's necessary to get your revenge. And what's the best revenge? To be super annoying right back! There are so many hilarious possibilities when it comes to driving your sister crazy. Just be warned that some of them might get you in serious trouble, so proceed at your own risk!

Method 1

Method 1 of 2:

Playing Practical Jokes

1
Steal something from her. One of the best ways to bug your sister is to steal her things.
- Sneak into her room and take something really important, like her iPod, her favorite pair of earrings, or the stuffed animal she sleeps with every night.
- When she confronts you about it, deny that you took it - you should practice your innocent face beforehand. You could also pretend to be really offended that she accused you.
- Make sure that you've hidden the item well, in case she decides to search your room for it. Then, when she's out of the house, put the item back exactly where you found it. She'll start to think she's gone crazy!
- Even better, if she's really really vain or has boatloads of makeup, hide it all (or just what she uses the most) and, when she accuses you of stealing it, just say something like, "Why would I steal it? I'm not vain like you!"
2
Hide her clothes. Everyone knows how much girls love their clothes, so what better way to annoy your sister than to hide them all?
- When she's out of the house, sneak into her room with a big bag and dump all of her clothes inside. Hide them somewhere she won't think to look for them, like the bathtub or the garden shed.
- She'll probably freak out when she sees that her wardrobe is empty, so have a good excuse prepared. Try telling her that your mom decided that she had too many clothes and gave them all away to charity! However, draw the line at hiding or vandalizing your sister's prom dress, wedding dress, or any clothes that are important to her, such as a shirt given to her by her dead grandmother.
3
Scare her. There's nothing more satisfying than giving your sister a good scare, especially if she screams!
- Plan your attack carefully. Lie in wait for her in a dark room, behind her bedroom door or behind the shower curtain in the bathroom.
- When she comes in, you have two options: you can either scream at the top of your lungs or creep up behind her and grab her - both can be really effective.
- For added effect, try wearing a scary clown mask or brandish a fake knife.
4
Cover her room with toilet paper. Another great practical joke that will definitely drive your sister crazy is to cover her room with toilet paper.
- Grab a roll from the bathroom and just go crazy. Try to zig-zag the paper across the room by hanging it from the ceiling light, the windows and the wardrobe.
- Cover her bed in piles of the stuff (or even put it in the bed). If you want to get really creative, soak some of the toilet paper in water and throw it at her walls, ceiling and mirror. This should make it stick.
- Just be warned that if your parents find out, you'll probably be the one who has to clean it up - so don't go too crazy!
5
Pretend she hurt you. Get your sister in trouble with your parents by pretending that she hurt you - either physically or emotionally.
- Just before they walk into a room, lie down on the ground in front of your sister and cry out, as if in pain. When your parent ask what's wrong, tell them she pushed you.
- Pinch your own arm so that it leaves a red mark, then tell your parents that your sister did it. They'll never believe that you intentionally hurt yourself, so she'll get in trouble.
- Tell your parents that your sister called you stupid, or ugly or that you have no friends - the meaner the better. She won't be able to prove that you made it up!
6
Annoy her while she's sleeping. Annoying your sister while she's sleeping is so easy to do, and produces some pretty hilarious results!
- One of the best practical jokes you can play is to squirt shaving foam or whipped cream into her hand and then tickle her nose. She'll try to scratch her nose and wind up with a face full of cream!
- Alternatively, you can try waking her up in the middle of the night. Wake her up in some annoying way, like jumping on her bed or poking her face. Tell her it's 8.30 am and she's going to be late for school. (If you're really clever, you'll change the time on her alarm clock as well.) Hopefully she'll get up in a panic and start getting dressed for school - even though it's really 5 am!
7
Throw water balloons at her. Water balloons are the perfect tool to bug your sister with, especially if she hates getting her hair wet!
- Get your hands on some water balloons, fill them with cold water and carefully tie the ends. Lie in wait for your sister (somewhere outdoors or your parents will kill you) and when she comes attack her with water balloons.
- It'll be extra funny if you wait until she's sunbathing with a bunch of friends in the garden, or hanging out with her boyfriend. Be warned though - soaking her with water balloons is sure to make her see red - so run away as fast as you can afterwards!
8
Turn off the light while she's in the bathroom. Have you ever been sitting on the toilet when someone accidentally turns off the light in the bathroom? Not fun, is it?
- Use this technique to bug your sister - especially if she's hogging the bathroom, again. It's easier if the light switch is on the outside, but if it's on the inside just open the door very quietly and flick it off before she notices.
- If you can, try locking the bathroom door from the outside, leaving her stuck inside in the dark. Don't leave her in there for too long though, have mercy!
- If your sister leaves the bathroom door unlocked while she's in the shower, you could also try sneaking in and flushing the toilet. Sometimes this will turn the shower water cold, which she'll hate!
9
Mess with her food and drink. Messing with your sister's food and drink is one surefire way to drive her up the wall!
- If you're sitting at the kitchen table and she has a glass of water or soda in front of her, point out the window and say "look!". When she turns back around, tell her you just spat in her drink (you don't actually need to spit in her drink, just say you did!) She'll be so disgusted, she'll have to pour the drink down the sink!
- If your sister is eating something tasty, like a muffin or a bar of chocolate, try grabbing it really quickly and licking it all over. She'll be so grossed out that she won't want it anymore and you'll get to eat it instead!
- If your sister is drinking a can of soda, wait until she puts it down somewhere and leaves the room. Then, very quickly, pour the rest of her soda down the drain and fill the can with milk (or some drink she hates) instead. Then when she comes back and takes a drink she'll be so surprised she might spit it out again.
- If you wanted to be really mean, you could put something like soy sauce or juice from the pickle jar into the can instead.
10
Send messages from her phone. Your sister probably always has her phone in her hands, so it may be tricky to pull this one off. But if you can manage to steal her phone somehow, this will be the best prank of all.
- Once you have the phone, go somewhere private to do your mischief. Look through her phonebook for the names of boys in her class, then send them all a message like "I have a massive crush on you. Wanna go on a date on Friday night?" Your sister will be mortified when she finds out!
- You could also message a few of her best friends saying something like "I am so mad at you right now...I'm telling everyone your secret". Be careful with this one though - you might end up starting a major catfight!
- If your sister has a smartphone, try logging into her Facebook or Instagram account from the apps on her phone. Take a picture of yourself and post it to her wall, saying something like "I have the best brother/sister in the whole world! I love him/her soooooo much". Your sister will go crazy when she sees it!
11
Make a splash.
- Get electric tape, duct tape or scotch tape.
- Stick a piece under the faucet. Leave a small part toward the front of the faucet uncovered.
- Make sure no tape is showing.
- When your sister turns on the faucet, the water will spray up and onto her; she will get soaked and you will crack up.

Method 2

Method 2 of 2:

Being Really Irritating

1
Sing an annoying song - constantly. Choose a really annoying song, like "La Cucaracha" or "The Birdie Song" and sing it or hum it constantly when your sister is around. Soon it'll drive her crazy!
- Alternatively, you could play a really annoying instrument, like the kazoo or a tambourine. Play it loudly when your sister is trying to do her homework or watch her favorite TV show.
- When she tells you to knock it off, act really offended and tell her she's interfering with your musical genius.
2
Imitate everything she says. This is the oldest trick in the book when it comes to annoying your sister, but it still works like a charm. Whenever your sister says anything, repeat it - it'll infuriate her pretty quickly!
- To make it even more annoying, put on a high-pitched, girly voice while you do it, and pretend that you can't pronounce your Rs properly, or that you have a lisp.
- If she tries to get clever and say something like "I'm an annoying little brat" just so you'll repeat it, outsmart her by changing the "I'm" to "you're", so you say "you're an annoying little brat" instead.
3
Stare at her all the time. Try to freak your sister out by staring at her constantly, without speaking. Do it at the breakfast table, while she's watching TV, or when you're in the car. Make your eyes really wide and blink as little as possible.
- Try sneaking into your sister's room in the morning, before she wakes up. Lean over her and place your face about on inch away from hers, staring at her. When she wakes up and the first thing she sees is your staring eyes she'll be completely freaked out!
- You could also go outside and stand outside her bedroom window. Then when she opens her curtains, you'll just appear in front of her! She'll probably scream!
4
Learn a language she doesn't understand. Try learning a few phrases (or curse words!) from a language that your sister doesn't understand, and say them to her over and over again. This will drive her crazy, especially if she tends to be a bit of a know-it-all!
- You could learn phrases from a real language, such as French or German, or from a made-up language, such as pig latin or gibberish.
- You could also just learn some big words in English that you know she won't understand. You don't need to use them in context or anything, just say them as if you know what they mean. Some good ones include malevolent, perfidious and animalistic.
5
Completely ignore her. Sometimes the best way to annoy your sister is not to do anything at all - just pretend she doesn't exist!
- Don't ever look at her or acknowledge her presence at all. She may not notice or care at first, but after a while it'll start to drive her crazy!
- Whenever she says something to you, don't reply, pretend you didn't hear anything. You could even look around you in a bewildered way and say something like "who said that?" or "did you hear that?"
- You can take this even further by pretending she doesn't even exist. When you set the table for dinner leave her place blank. Or when anyone mentions her name, look really confused and ask "who?"
6
Make up an annoying nickname for her. Calling your sister by an annoying nickname is one surefire way to get her blood boiling.
- Come up with a nickname that rhymes with her real name, like if her name is Hannah or Anna, you could call her "banana". Or if her name is Lucy, you could call her "goosey".
- Or else just come up with something really offensive. For example, you could refer to her as "The Squid" or "dog-face" or "Miss Piggy".
7
If you want to get your sister really mad, you should take her diary, where she writes all of her innermost thoughts and secrets.
- When you're done, you can leave the diary somewhere obvious, along with a note that says something like "I know all your secrets". In fact, you don't even need to read her diary (nor should you), you just need to make her think you did.
- However, if you do decide to read it (which you shouldn't), try to memorize some of the best bits. Then you can recite them back to her when she least expects it. For example, when she's doing her homework you could walk into the room and say "I wish Ryan would notice me, but he acts like I'm invisible." in a high-pitched, girly voice. Then you should run for your life!
8
Poke her. Simple, but effective - you can drive your sister crazy just by poking her over and over again. Do it in the car, at the dinner table, while she's watching TV, when she's in bed - basically whenever you can get close to her!
- You can either poke her in the stomach, where it tickles or poke her face, where it's just really annoying. You could even make a face while you poke her and say something like "Ewww, what is that?" This will make her really paranoid - she'll think she has a huge pimple or something!
- Just be warned that sisters tend to poke back - so don't give it if you can't take it!
9
Laugh at everything she says. Another good way to bug your sister is to laugh at absolutely everything she says, even if she's being completely serious.
- This will drive her particularly crazy if she's upset about something, such as a fight with her friend or getting a bad grade at school. Laugh and point, like Nelson from the Simpsons - "haha!"
- Or else you can laugh hysterically when she actually tries to make a joke or be funny. But keep laughing for a really long time, until it's obvious that you're just being sarcastic.
10
Wear her clothes and pretend you're her. Sneak into her room and snag some of her clothes. The more she likes those particular items, the better.
- Dress like her. Use the same combination of skirt and blouse that she wears. If your feet are the same size or smaller, put on the shoes she'd wear with that dress.
- Arrange your hair in a similar way if you can. If not, find a wig somewhere.
- Come down to breakfast one morning as her. Mimic her speech patterns, hand movements and stuff like that. It won't take long before she howls for your mom or dad to make you stop!

If you throw the water balloon at the back of her head and for some reason she falls, she may get hurt. Remember: you're just trying to bother her, not kill her. Not only that, make sure any objects she's holding are waterproof - especially electronics. You don't want to damage anything.
