Duff

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.

Designated Ugly Fat Friend

A DUFF doesn't actually have to be fat or ugly, just less attractive than the people they are with

Also, a person can be one of the hottest in one group of friends, and the least hot (and therefore the Duff) in an other group

The duff is the less attractive friend and therefore easier to talk to than the hotter friend you are trying to score
