To slap someone across the face with a slice of pizza. Like a bitch slap but with pizza, preferably with hot greasy pizza.
A fight broke out in the cafeteria and both kids laid down the pizza slap on each other and suffered burns to the face.

When you go into a room and shit into your hand, then run out wildly and slap someone in the face while the shit is in your hand.

When someone's been in a fight and they've been hit in the head so much that it makes them act silly and crazy. Sort of like punch drunk.
After getting the crap beat out of him, he got so slap happy that he couldn't stop giggling, and he didn't know what was going on.
