Looking at you for too long.
Don't. Touch. His. Stick.
Calling your mom on the phone.
Liking your facebook page.
Eating the same brand of oranges as you do.
Mentioning you on twitter.
Grunting really loudly.
Farting in your general direction.
Logging into his Barbie.com account.
Having a wet dream about you.
Doing the robot.
Lip syncing to "What, What, in the Butt."
Wearing a purple hat.
Masturbating to Justin Bieber in a tutu.
Playing his music too loud.
Hitting you with his purse.
and finally by Daniel Briere can give you aids by not wearing a bra.
