Got to love people that can't handle alcohol, or, it makes them think they're tough. You're at a football game. Have fun with the friendly banter, but if your fragile ego can't handle it, don't attend and/or drink.
When I was at the Saints - Titans game the other weekend, there was some mid 20's male Titans fan sitting in the row in front of me. You could see his drunk meter elevating as the game wore on. By the end, there was a 60-70 year old Saints fan woman who was cheering, and this idiot fan (and I am not exaggerating) looked over and yelled at her "Shut the BEEP up. I would BEEP you up". A person in my party piped up "Excuse me? Why don't you talk to me like that?". Then this guy starts running his mouth at us. Finally, I got a tap on my shoulder from this lady behind me. I spun around and she said "Hey, tell him this guy up here wants to talk to him". I look up and it was a police officer. He came down and kicked him out. Everybody clapped.
