DUFF

It means "Designated Ugly Fat Friend". They don't have to be any of those, but that doesn't mean they don't have friends more attractive than them. The DUFF is basically the least attractive one in the group.

"She's cute, but her friends are hotter. She must be the DUFF."

"He's the youngest in the team and acts as the Gatekeeper to the rest of the team. He's a DUFF."

"That teacher is being left out from other conversations... He's a teacher DUFF."

DUFF

Abv. For Designated Ugly Fat Friend. Usually the one person more approachable in a group and the one who is less attractive than all the others in the group. Sometimes a girl will approach a DUFF and start to flirt but after a while will begin to ask questions about another hotter member of the group.

Man #1: Dude, that's your job as the DUFF
Man#2: What did you just say to me?
Man#1: You're a DUFF, Designated Ugly Fat Friend.
Man#2: That's so messed up.
