A pizza is what you see on the floor after severe nausea when you feel ill, so you puke and throw up.
Your guts content comes from the acid stomach up and through your mouth and falls down on the floor or ground.
Even if your not intoxicated it will look like a pizza when you puke and "lay a pizza".
The effect might not be calmed down by ordering a real take away pizza the minute after, to fill the stomach.

The perfect meal--an open-faced pie using tomato sauce, cheese, and any manner of meat toppings. In addition to the standard, medium-thick-crust pizza, there are two major American varieties: New York style, also called thin crust; and Chicago style, also called 'deep-dish' or (more accurately) 'stuffed' pizza.

A delicious, round piece of dough that comes in square boxes for some strange reason.

Greatest food ever. Otherwise known as the 7th food group and the most needed.

Hands down the best tasting, most versatile and convenient food in the world.
