Mostly speaking for myself here, but I think I might also speak for other people here.
When I curse around, in any language, I mostly use terms like, fuck, dick, cunt, shit, ass, gay, idiot, asshole etc. With my friends I also like to make jokes about various "races" if you know what I mean.
Thats not meant as "hating", its just cursing, and making jokes about Orcs (orcs stand for a random race/nationality in this case) is just EASY, and its fun for me, I dont think about it.
I like cursing, I like drinking and I like stupid jokes - no real offence meant.
