DUFF

Abv. For Designated Ugly Fat Friend. Usually the one person more approachable in a group and the one who is less attractive than all the others in the group. Sometimes a girl will approach a DUFF and start to flirt but after a while will begin to ask questions about another hotter member of the group.

Man #1: Dude, that's your job as the DUFF
Man#2: What did you just say to me?
Man#1: You're a DUFF, Designated Ugly Fat Friend.
Man#2: That's so messed up.

puff duff

When you have too much fun (read: alcohol) and you're lame the next day and stay in bed and not participate in vacation activities.

In Jamaica, Jim partied too hard and the next day stayed in and was a total puff duff.
