Lol? more like 90% of uneducates? * off I've only had two people ask me if I miss pelt rogue or meant Rouge.
Everyone knows rouge by the perfume anyway. Unless you've never talked to a girl which is understandable.
I'm going to go with blitz on this one, it's more like 90% of mmo players.
Most of them don't MESSAGE you about it of course - they just look at you, /facepalm, and move on.
Most everyone KNOWS the word 'rouge' but also most everyone has watched general chat for 6+ years and watched ROGUE misspelled at least 90% of the time. So no, I'd guess most people just assume it's a dumb misspelling, not a deliberate name.
(BTW generally rouge is a category of cosmetic, not a perfume (it may well be a name of a specific perfume, sure).)
