duff

Designated Ugly Fat Friend

A DUFF doesn't actually have to be fat or ugly, just less attractive than the people they are with

Also, a person can be one of the hottest in one group of friends, and the least hot (and therefore the Duff) in an other group

The duff is the less attractive friend and therefore easier to talk to than the hotter friend you are trying to score

Duff

DUFF - Designated Ugly Fat Friend.

Doesnt have to be fat or ugly. The weak link in the group of girls. The least attractive but it the most approachable. Use her to speak to the girl in group you want to score with.

"Damn Cindy so hot, how do i even get a chance to speak to her?"

" its simple my friend, get to know her DUFF Sarah & youre in"
