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

Duff

Designated Ugly Fat Friend.

Its one person in a group who makes everyone else in the group look better. The duff doesnt have to be ugly or fat.

Hannah is clearly the duff of the group!

Hilary Duff

A Hilary Duff is someone who tries way to hard to be sexy but fails miserably; she looks like she completely does not want to do it, but does want to do it.

Did you see that new Miley Cyrus video? She was totally being a Hilary Duff!
