I'm only believing this to a point. He says he's blitzed, his GF is kind of a "rebel" type, yet they were doing absolutely nothing, and lo and behold they were being picked on. I'm 100% sure this is what happened.
As a side note, I've been to half a dozen away games, so I'm not an expert compared to a lot of people, but guess what, fans tend to get pissed when you're cheering against their team. I've been told to sit down, shut up, go home, called a hick, red neck, etc, and I dont care. For the most part away games are fun, sometimes you run into jerks. Its what happens, you do your best to have fun, and cheer your team....
