B.U.F.F

Big Ugly Fat Fuck, aka, that annoying guy who considers himself to be all that, but in reality said person is just a douche bag. The term is typically used in veiled sarcasm by everyone else around said person, since he is far too oblivious to the intended meaning.

Troy: "Hey Jerry, you're looking pretty B.U.F.F. there, you been working out?"

Jerry: "What? Nah, I'm just naturally this way."

Steve: (to Troy, after Jerry walks away) "Did you really mean that?"

Troy: "Yep, he really is a Big Ugly Fat Fuck"
