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.
