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"
