Designated Ugly Fat Friend. A book written by Kody Keplinger. Also a movie. Basically it's the person in a group of friends that is less popular than the rest, isn't as pretty/handsome, or they are a bit thicker than the rest. Sometimes it can be a freshman with a group of juniors or seniors. The Duff can be someone other people go to to get information on the Duff's hotter friends.
Emily = The Duff
Hot guy : Yo Emily!
Emily : *omg a hot guy is actually talking to me!!*
Hot guy : hey, do you know if your friend Hannah has a date to homecoming? I want to ask her to go with me.

A Scandinavian drinking game that can be played by two or more players.
Played in a circle the participants hit a beer can against their head twice with considerable impact (hence duff duff) and then pass the same beer can to their left. The next participant does the same and that continues until the can springs a leak.
The person whose head caused the leak then needs to open the can and down it.
The player to the loser's left takes a fresh can and the game continues.
