Pizzaboxing
Doing a chick from behind while you have a box of pizza, can be any kind of pizza, and you put the box on her back and eat the pizza during hawt sexual intercourse.
Guy #1: "The other night I was totally pizzaboxing this chick, it was nuts. She was bent over and I was fucking her so hard she screamed 'OHHHH FUCK!!! YEAH!!!!!!' and the pizza box fell off her back."

Guy #2: "Dude that's fuckin' tight!"
