Get the DUFFmug. 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.

Get the Duffmug. In online gaming, a duff is an inexperienced player who uses a new account to deceive other players into thinking he's a experienced player (smurf). The purpose is to frighten other player to thinking they are a experienced player and make them play worse thinking they have already lost. The expected result is to get easy wins thinking they are skilled by tricking the other players and get wins. The outcome is shown pretty quickly when the obviously don't have the experience to keep up after a few games.
So yesterday while playing CoD I saw this new account and was frighten it was a smurf, it was pretty easy to realize it was just a duff and I pwned him. Got to love dumb noobs.
