Duff Thrust

Simply the coolest move ever to be made by the most awesomest of mascots ever created. Is executed by holding the hip bones with both hands and thrusting the pelvis. But only Duff Man can do a Duff Thrust.
Is used to portray smugness,happiness,or glee or even acknowledgement.

Duffman?!! :O
Oh Yea! *Duff Thrust*

Duff Man,what're you doing?!
Duff Man is Duff Thrusting. Oh yea.

DUFF

(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.

Man 1: "Hey do you know if that hot girl is single?"
Man 2: "I don't know, go ask her DUFF"
