Every DM hates problem players, but what happens when one goes too far? In my recently finished campaign, which I am boundlessly proud of, there was one player who showed complete disregard for the game, table etiquette, story, ect. During gameplay he would show utter disrespect for me and the other players, not caring to even pronounce the NPCs names correctly. He would also go out of his way to ruin intense, dramatic, and emotional moments in the game by speaking in an obnoxious and offensive Australian. Not to mention he refused to role play his character, at the end I asked everyone what there characters did after the adventure was over, his reply was "Nothing" Everyone else loved the campaign, I don't think I was doing anything wrong, and I'm not really in a position to kick him out, but I need to do something.
Uh, no way, eh; you'd still have all the same problems only with a two-four attached. Beauty!Sounds like he is just a Method Actor - try Polymorphing him into a Canadian. I think you will find that solves most of your problems, eh.

Australian here.
What was offensive and obnoxious about the accent?
I assume he means a bad imitation of an Australian accent, but I don't want to speak for him.
