DUFF

(Designated Ugly Fat Friend) A DUFF doesn't always have to be fat or ugly, sometimes a DUFF can be cute, but they're there to make the rest of the group look better and to be the approachable one for anyone seeking inside info.

Man 1: "Hey do you know if that hot girl is single?"
Man 2: "I don't know, go ask her DUFF"

DUFF

Desiganted Ugly Fat Friend. A common acronym used in male cliques. Used to refer to the girl that the "hot chicks" bring along to distract the "Wingman" (every male clique has one, his job is to intercept the DUFF.) so the ycan have the more desirable males of the group.

"Dude, you sooooo got the DUFF tonight."
