Definitely. Used in an offhand way to appear casual and cool, when really everyone know's the person is a twit.

"Yeah, I'll be getting drunk tonight, deffas!!!"

derfing

When a guy and girl are sexually intimate, the practice of the guy to alternate between bottom and top holes (anus and vagina). No particular pattern of action is required, and the switch-off can be completely random (ie: top, top, bottom, top, bottom, top, bottom, bottom, bottom, top, fist).

Create special patterns to signify festive or celebratory events and occassions; re-live these occassions through fantastic, nostalgic sexual practices!

Donnie: Tim was derfing Julie and covered her vagina with shit.
Darcy: Goddam! O_O

Derf

A word used as a censor for the word "Fuck". Can be used in any tense that "Fuck" can.

Derific

The opposite of Terrific, when someone or something fails, the feat is Derific.

His inability to follow directions is derific!
