The Designated (/Dumb) Ugly Fat Friend.

The cock-blocking friend of the hot chick you're trying to hook up with, often the target of the wingman.

I was totally in with this chick and then her D.U.F.F. totally cock-blocked me!

D.U.F.

Meaning, "Designated Ugly friend."

A pretty girl always has pretty friends, but when she wants to snag guys, she brings along her D.U.F. only.
So who is the guys going to hit on?

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"
