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.

Steve: (to Troy, after Jerry walks away) "Did you really mean that?"
Troy: "Yep, he really is a Big Ugly Fat Fuck"

Sorta like the term D.U.F.F, meaning designated ugly fat friend, the word B.U.F.F means, black ugly fat friend.
