derf sweat

When playing in extreme sports or running. Or fucking for so long and hard that you begin to perspire on your derf. (space between your balls and asshole.)

Shit Sydney! You made me get derf sweat! But damn that pussy was good!

Derf Run

A necessarily late night quest to the closest/farthest 7-11. At least 3 of the four derf meisters must be involved.

For every extra 7-11 hit up, a prefix must be added, i.e. double, triple, double-double, etc.

Douchebag: Wait, what's a derf run?
Derfmeister: WHAT'S A DERF RUN? Why, it's the most wonderful magical thing of all. And it only happens once a year, every week!

Derf Snort

A human being with the hair of a troll and looks petrifyingly ugly. Sometimes is as fat as a whale.

Omg that girl is such a derf snort, prancing around in her ugliness.

Derf Smash

When one of your friends attempts to become the incredible hulk when drunk and no one will give them more alcohol.

Fred went derf smash on the table and broke it after everyone hid the alcohol from his drunk ass.

derf

(Definition 1): The extra skin that allows your balls to swing out, so you don't shit on them. (Although usually covered in hair, there have been reports of hairless and albino derf spottings in the wild);
(Definition 2): sweaty, stinky, beneath you, Flappy Fringered Bassist

(Definition 1): This Guy I know was in a bad car accident and broke his derf. Doctor told him it might never be the same.
(Definition 2): That guy they caught spanking it in the Mens room is such a Derf.

[ Berf-Derf ]

Something that is Dumb,stupid, boring, growing tired of. could be shortened to just Berf.

*** note ** this made #1 on the "reader slanguage" in FHM magazine sent in by myself (march 2006)

-Man that movie was Berf-Derf , I walked out the theater.

-If someone just told you a supid joke: you say " Berf-derf ".

- Getting tired or bored at a joint or club?? just say "man this is Berf-derf , lets roll".
