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.

Duff
Designated. Ugly. Fat. Friend
Ex. Britny is the duff in the group
Lisa and jen are hotties or the atravtive one and britney is ugly and fat compared to them
It can be guys (not alway ugly or fat) lets say they are freshmen and are like wingmen to upperclass men
*They are the ones who the girls go to ask if the jocks or alist guys in the group are single

The 2015 movie "Duff" is about a girl who is the duff in her group of friends at highschool who was unaware that she was the duff and was set oit to change it

"Duff " is not a positive thing to be called
