yea, I used it once before. I never knew it until someone told me the "you know what" word is offensive

then i wikied it and realised it was REALLY offensive
(wiki definition to it) But i believe people used the word without knowing the offensive history of it

i just thought it was a short way to write "Japanese" at first

I only seem to see it used in posts about CDs.
eg
"I just bought *WHATEVER CD* j$p version"
oh, btw is "JP" offensive in anyway? just incase
