The vomit of someone who has been drinking too much, usually big and in a round shape. (Used in the Netherlands as 'vloerpizza', usually by students.)
Aww man, did you make that floorpizza over there?

Pizza that was left in the box on the floor during a night of drinking, usually found by a near by passed out guest laying next to it the following day.
