FURK is an acronym for "For Unlawful Rectal Knowledge". FURK is when a man is having sexual intercouse with a woman from behind or doggy style in her vagina, and with one quick motion puts his penis in her anus and plays it off as a total accident. A man will FURK his woman in an attempt to see her reaction to anal sex.

Doing something for fun that happens to coincide with your field of expertise. Similar to "geeking out", but at a heightened level of intensity because it engages both the work ethic and the recreational desires of the participants.
