When you poop and your ass burns just as much as your mouth did after eating something spicy; such as from buffalo wings. It can also be associated with having to poop quickly right after eating the spicy food.
I got buffalo ass after eating those hot wings last night.
Buffalo Ass: When a girl has such a big ass, its looks like a buffalo from the back.
Damn bro, that chick has a major buffalo ass !
