Get the DUFFmug. 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."

Get the Duffmug. duff
Duff
Designated. Ugly. Fat. Friend
Ex. Britny is the duff in the group
Lisa and jen are hotties or the atravtive one and britney is ugly and fat compared to them
It can be guys (not alway ugly or fat) lets say they are freshmen and are like wingmen to upperclass men
*They are the ones who the girls go to ask if the jocks or alist guys in the group are single
The 2015 movie "Duff" is about a girl who is the duff in her group of friends at highschool who was unaware that she was the duff and was set oit to change it
"Duff " is not a positive thing to be called
