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.

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.

(Designated Ugly Fat Friend) A DUFF doesn't always have to be fat or ugly, sometimes a DUFF can be cute, but they're there to make the rest of the group look better and to be the approachable one for anyone seeking inside info.

Desiganted Ugly Fat Friend. A common acronym used in male cliques. Used to refer to the girl that the "hot chicks" bring along to distract the "Wingman" (every male clique has one, his job is to intercept the DUFF.) so the ycan have the more desirable males of the group.
