duff

Designated Ugly Fat Friend

Two hot chicks at a bar will have a really nasty fat ugly bitch hanging out with them, refered to as a "DUFF".

"Wow that fat DUFF is hanging out with those two attractive ladies, too bad."

Duffelbagging

When a man is so hammered drunk that he can't maintain a erection, so he throws his half flaccid hog into the bitches snatch like a duffel bag in the trunk of a car.

Mason: So how did things go with Kerry the other night?
Joe: Well I was shitfaced and she wanted to fuck, so I was Duffelbagging her for about 10 minutes then I fell asleep
Mason: Did she call back today?
Joe: No....

Duffie

Duffie is a very loyal girl. If she falls in love with you, she'll never cheat on you. She's usually a bit of a tomboy, but very pretty.
She also has a good sense of humor and can be very sarcastic. Duffie is nearly perfect.

''I made Duffie my girlfriend.''

''Wow, good job! You'll be happy together!''

Duffing up

Female equivalent of beating up. Not so violent and involves a lot of pushing and the occasional pinch. From the series "Confessions of Georgia Nicholson".

Jes was duffing up on Ellen. Jes was winning.

Duff Gen

Incorrect information. May have had origins in the RAF.
