BYOBB = Bring Your Own Brown Bag
Typically a butterface, who as a great
body that you would fuck, but a
face so
hideous you need to put a brown bag over it when your fucking her.
Guy 1: Yo
man, Kristina has a bangin body, but her face is whack.
Guy 2: Dude just BYOBB.
Guy 1: Oh shit, bring your own brown bag, yeah that would
work so I don't need to see her
face while I'm gettin it in.
