D.U.F.F.

An abbreviation for 'Designated Ugly Fat Friend'. Often in many large groups of women (usually adolecents) there will be a D.U.F.F. as a means to look better by comparison.

I only hang out with her becuase I need a D.U.F.F., otherwise, she'd be, so, history.

D.U.F.F.

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!

I'll take her, while you distract her D.U.F.F.!
