behaviors like this isn't to be proud of.... .. . from both players. Being a douche yelling in a mic is lame, but it is equally lame to antagonist and annoy someone for no other reason than to annoy someone... it is practically the same offense to good gamers. IMO online gaming would be way better with out either of these types of things happening. Just decline a rematch and move on to better things, and by doing that, means BOTH players get to move on to better things.
This is terrible behavior that just ruins online gaming. Why would you go into a friendly room of people hanging out together and boosting minding their own business and having fun and then not play by the room rules, troll them and just ruin their game experience... no reason, just another looser online.... I miss the arcade
