Get the DUFFmug. That place on the human body (particularly the female body) where the body makes contact when sitting-down, i.e. the erogenous area of the butt.

Get the Duffmug. 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

Get the The Texas Beto Duff Fluffermug. A cocktail consisting of equal parts Cynar, Campari, and gin with a splash of soda and an orange twist.
"Hey bartender, I'd like a drink that's neither too sweet not too bitter."
" How about a Duff?"
"Perfect!"
" How about a Duff?"
"Perfect!"

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.
