Dirty Duff 

A Dirty Duff is a sex move inspired by the great Garrett Duffy, the most badass baseball pitcher to ever play for Red Mountain High School. A Dirty Duff is a signature move in which the male shoves a baseball bat into the woman's vagina and then proceeds to throw batting practice to the girl, the girl will swing the bat using the muscles in her pussy and clitoris and hit the ball.This is really a revolutionary form of exercise and can be very beneficial for the woman as it strengthens her pussy muscles and mental toughness. Using this move you really can hit a homerun, no pun intended.

Guy 1:"I saw you leaving school with Mackenzie the other day."

Guy 2: " You know I took her straight home and gave her that Dirty Duff."

Mackenzie:*squirt squirt squirt*

The act of shitting on your own balls, preferably diarrhea, and then placing your balls in a partners mouth.

Me and Angie had a crazy night last night, we went out to get tacos and then I dirty duffelbagged her.

Take plastic king cobra snake and shove up her ass and yours at the same time. Then forcefully make her yell "wow" loudly while throwing her hands in the air. Then wipe shit from the snake on chest and use a "squeegee" to clean it off and then lick it off.

Nate: "Yo do you know how duff did with the 1st grader last night"
Mike: "Ya man he tried the dirty duffy but couldnt get it done"
Nate: "Oh figures hahaha"
