Boo! (game) Seven students, guy, then girl, then guy, etc. line up, side by side, with informed female student at the end. Have them face sideways, then turn and say, “Boo!” to the next person after the person on the other side has said, “Boo!” to them. Next, they “Boo!” each other back down the line again (going the other direction).

The third time the leader behind the informed girl gives her a pie behind her back. She pies the guy in front of her when he turns around to “Boo” her. Be sure to choose a good sport to get pied and have a towel handy.
