DUFF

Designated Ugly Fat Friend .

In a group of friends there is always a duff that looks bad and make their friends look good . A duff can be easy to talk to , sweet and friendly . Everyone wants to be friends with them to get the hotties . A duff can be smart , funny but never cute or sexy .

I got her number from the duff .
