The term "JF" is a verb recently brought to world attention in early 2007. Based on the exploits of a certain employee of an international internet corporation, "JF" is commnoly used as a verb meaning to sodomise dominantly.

In Thailand, the term "JF" has almost God-like qualities, due most likely to the hig quantity of sodomised locals who endured a great "JF-ing".

In addtion to signify anal pounding, it can also be used to mean "get screwed", as in getting screwed in the work place
I JF'd her last night!

I would love to JF that girl, but I don't have any lube.

In the workplace: "This idiot stole my presentation and I got JF'd royally!"

Common acronym used as an insult towards guys. The true meaning of JF is top secret, but in general applies to any player, jackass, bonehead, jerk, or piece of crap boy that you have had unfortunate dealings with.
"So then I found out he said the exact same thing to two other girls."
"Ew, what a freaking JF."
