Last night, I had a game - a team game, my Exorcists and a friend's Sisters of Battle vs Space Wolves and Imperial Guard - and one of my opponents really crossed the line. Every time he popped a transport or killed a model, he would cheer and pump his arms in the air and shout "Boom! Get that sh*t off my table! No f^cking Sisters of Battle here!" and so on.
It was notable in that it really was too much. I've played against opponents who said things like "The Emperor protects!" when their models passed cover saves or "Die filthy xenos!" as they rolled their to-hit dice... but somehow, this guy crossed a line. It was too much, too frequently, and too much profanity, and we almost ended the game over it.
I'd like to open a thread to talk about the difference between "good" smack talk and "bad" smack talk. Clearly, the difference exists, and I think we can improve the entire community if we can identify it.
I've got further ideas about this, but I don't want to write an essay here. What are your thoughts?
