fatboy

A large hamburger generally found in Winnipeg, Manitoba. It consists of a hamburger patty, chili, quartered dill pickle, onions, mustard and a lot of mayonnaise. Usually the burger is too tall to fit in your mouth so you eat it by squeezing or using a fork or both.

I ate a fatboy with chili fries and now I don'y have room for a shake.
