It was so rude of him ... yelling constantly at the refs and the team and being super obnoxious. It wasn't your typical stuff ... he was "that guy". My kids were uncomfortable and didn't want to be there. Thanks dude, for ruining the game for those around you. In fact, the people next to me did end up leaving because they couldn't take it any more.
I finally told him to please calm down, and it was much better.
