A Bea is a butt-ugly meangirl. Bea's are often self centered and big fat bitches. Any guy who so much as lays eyes on her is at risk of pissing theur pants or even hurling at the sight of her revolting face and/or body. Don't let her fool you!
Dude: "AHHH! its Bea! im scarred for life!"
Friend: *shits himself*
