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 .

Duff 

That place on the human body (particularly the female body) where the body makes contact when sitting-down, i.e. the erogenous area of the butt.

I'll bet her duff is as sweet as candy!

Duff 

A cocktail consisting of equal parts Cynar, Campari, and gin with a splash of soda and an orange twist.

"Hey bartender, I'd like a drink that's neither too sweet not too bitter."
" How about a Duff?"
"Perfect!"
