Montana Duffel Bag

This lovely little technique is when you shit in a bag, put it on a girl's head, and fuck her in the ass. Hold the bag really tight, but don't kill the bitch. Instead, when she's about to pass out you take the bag off and slap her in the face.

Derek gave Danielle a Montana Duffel Bag when they got home

The act of two men double teaming a girl sexually with their penis's (one in the vagina and one in the mouth) while suspending her in air by holding her legs and arms up like a piece of luggage.

Duffication 

When railing a girl doggy style a man places two fingers in the females asshole. Once the fingers are inserted into the asshole the male attempts to use those fingers to masturbate himself through her asshole. The name is mixture of defication and masturbation.

Man I tried to give her the duffication but when I tried to get that second finger in she got pissed.

duffer

The Designated Ugly Fat Friend found in a group of girls out on the town. She may be a Cockblocker unless your group of guys has someone drunk enough to take her attention away from ruining your night.

"Hey Joe, you take care of the DUFFer so I can get to the hot one."

"Dude, why do I always have to do that?"
