Machine Gun Butt: When you have the horrible shits that shoot out your ass fast and violent, like machine gun fire. Usually very wet, and very loud.

Person 1: Damn bro, what the hell just went down in that bathroom? And why are you sweating like crazy?

Person 2: MGB dude... I didn't think I was gonna make it out alive.
