Two girls conversing about the two dudes they did that night:
Chick 1:"Oh my godthat dude had soo much Butt Fuzz"
Chick 2:"What?! that's disgusting! mine shaved his!"
Also known as a raspberry, or in some circles, a "zerbert"...a fuzzbutt is the planting of one's lips on a body part of another...and blowing. Creating a "toot" like sound. Often done to babies' stomachs.
