Get the D.U.F.Fmug. Literally stands for Designated Ugly Fat Friend. This is the bitch who comes out of no where to cockblock you when you are about to get a chick home with you. She is often recognizable by her fat ass, bad hair and sour disposition. Her main goal of the night is to fend off any advances on her friend so she will have company at the diner when she is stuffing her fat face with an omelet and a side of disco fries while she bitches about anyone and everyone. The D.U.F.F can be defeated with a high level wingman, but you will be expected to return the favor; a job not for the faint of heart. A naked D.U.F.F often smells like a box of crayons.
"Dude, I was about to bag this chick, but then her army of D.U.F.F's came out of no where and pulled her away. She must be a Volleyball player!"
"Did you Fuck the chick at the party?"
"No Fuckhead, I got Duffed!"

Get the D.U.F.Fmug. abv. for Designated Ugly Fat Friend; Term men use to describe a fatter, less attractive friend, a woman brings with her to a party or social gathering to make herself look better by comparison. In some cases the more attractive woman will not "put out" for any male, unless one of his friends "takes one for the team" and "hits" the Duff.
