When someone is drunk beyond belief. Drunk to the point where homo-sexual behaviour is as standard as breathing. Licking somebody's face is more appropriate than hand shaking.
To get your ass kicked REALLY badly. If you got "duffed", you didn't just get punched in the face, hit the floor and kicked once or twice hard... you got hit in the face, hit the ground, then got hit in the face several more times, possibly had your head bashed into the cement, got kicked in the ears, neck, kidneys and various other soft spots on your body.
"Yung, that nigga D-Set laid up in the hospital. He smoked up that whole QP he was fronted by main man and got duffed."
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.
