Mhh, those guys must've gone really overboard, In sPvP I personally used the words: idiot/idiotic, moron/moronic, retard/retarded, noob (which wasn't really an insult just a question wether they were new, although I should've used newb but people don't know the difference anyways so meh)
And I was in the clear, ofcourse usually it wasn't adressed to specific people more like, "why won't these retards help me destroy the treb

"
Better sleep up to avoid crankyness next BWE/in game when I'm doing sPvP
