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.

Heather was duff hunting looking for a friend fatter, dumber, and uglier than her so maybe the boys would notice her.

The act of having a Thoroughbreed studding horse take Mr. Beto O. up his loose caboose. This demonstration requires an armed man dressed like Tonto to hold the reigns of the horse whle the every-willing Beto O. is mounted and studded. During this punishment of Mr Beto for his recent demonstrations of ignorance and lack of empathy, long time NRA member, William Duff will fire 10 rounds of bee bees at Mr Beto's genitalia to further excite the horse and Beto. At the moment of climax, Mr. Duff will begin the chorus of Pour Some Sugar on Me that Beto will continue until he collapses on the ground in total exhaustian. Tonto will offer a warm towel to Beto and escort him away from Silver the Studdly Horse. Optional: If avaialble, you may add a fully dressed look a like of The Lone Ranger.
After seeing some recent political nonsense from Mr Beto, I believe he must be punished and pay for his wrong doing by performing the Texas Beto Duff Fluffer
