Heh. Haven't seen that one except here on OCDO. Most people are not going to come up with that definition of "FUQ" especially given how it can/would be pronounced as a word. Depending on how you choose to pronounce the "Q", it comes across either as "da fuq?" as in "WTF?"....or "F you"
that was part of the humor in creating it haha. my exploitation of it turned into:
DAFUQ! please (damnit all, fair user quote, please) haha
eye95 started it, and the few of us that were in that thread started spreading it and watching the funnyness unfold in other threads that it gets used in haha
