It is a safe way of expressing "Fuck You Ass Hole" in an IM or email while you are at work fucking off.
When my friend Arend IM'ed me at work saying something stupid that he thought was funny, but wasn't, I simply responded in the most mature way possible by typing in "fuahole"... I showed him! :p
Originally derived from FU A-Hole, short for "Fuck you asshole."
However, when used once, it sounded more like FUA Hole, and FUA sounds like a club.
Therefore, the revised definition is the meeting place for the club: FUA.
FUA has yet to be defined as of September 13, 2006
