Making a "queef" style noise with your penis. Involves getting the air in your urinary tract to form a vacuum - letting the air out with a PRRRRRUITT-sound.

A deef can mean a few things. But here's how cool people use it...

1. The act of ruining a fun situation or to increase the amount of faggotry within a given area. Like saying "man you deefin' up the place" or "man, jefferey be str8 deefin'"

2. Deef is also how homeless negroes say "thief"

3. Dick queef.
1. "that guy is kicking us out of the skatespot" "well he a deef anyways..."

2. homeless negro: "hey man that guy stole my cigarettes, he a damn deef"

3 fag: "i just deefed in your ass"
receiving fag: "neato"
