Top Definition
A person (or persons) who bursts in un-annouced, especially with the intent of catching you while you're masturbating (fapping). sometimes accompanying the surprise entry with a loud shout of "FAP PATROL!!"

Can also refer to a pet who approaches you while masturbating and tries to lick or touch your genitals.

Bonus points if the victim is interupted while ejaculating.
(Joe is on his bed fapping to a porno mag)
(Bob bursts into the room)
Bob: "FAP PATROL!!!"
Joe: "WTF you gaywad!!"
