When one, in the heat of passion, poops in a girl's (or guy's) mouth, then performs an uppercut on the receiver's chin causing the feces to scatter all over the place of business.
"Dude, I took a dump in this girl's mouth, then uppercut her chin and my poo went EVERYWHERE! It was the nastiest Frowny Brownie ever!"
