look up any word, like blumpkin:
Taking an overly powerful rip from the bong and consequentially having one's mouth area covered in bong water.

Specifically, when the bong water is old and has nasty shit floating around in it.
Bro 1: Damn dude that was a Huuuge rip... I think the biggest of my life yo...
Bro 2: And you got the bong beard to prove it.
Bro 1: Aw damn that shit's nasty
