Last I checked. You were supposed to boo and be "negative" to the opposition as much as possible. Not cheer the opposing team on. That's so lame. "OK guys while you aren't my favorite team, might nice effort out there".
Wanna change the goal song? Hell by Foo Fighters. I could see that working.
Um what? You clearly have no idea what you're talking about. We're supposed to be supporting our team first and foremost. "This is our house" is a chant that shows support for our team.
Believe it or not, we go to games to cheer our team on. Or at least I do.
