At my old martial arts school in NJ, you don't trash talk. You don't even need to call me a cunt to show disrespect, you simply need to fail to bow out. Should I assume you are a juvenile, immature dick if you fail to bow out after a soccer match? Of course not.

In much the same way, there are sporting events where witty banter about "yo momma" is considered acceptable behavior. No disrespect is intended, and none should be taken. It's just the culture of the game.

If you want to declare your particular set of conventions superior to all the others, be my guest.
