when the kid in front of you gets so bored, they go flip shit crazy, turn around and draw on your paper until you get an F.
Kid 1 : *sitting quietly doing work*
Kid 2: *turns around and draws all over kid 1's paper with pen.
Kid 1: " DUDE wtf!?!?!"
Teacher: *grabs paper and puts F on it*
Kid 3: Bro, you just got page raped.
