I always thought at an NFL game the crowd yelled "Let's go D!!" But I just read they chant IN-COMP-LETE =0 No wonder they never do good when I'm watching and yelling!
You gotta yell the right thing or it doesn't work. Also when two American teams play against eachother you can't go wrong by chanting 'USA, USA, USA'.
At the hockey games here people would chant "WE WANT TACOS" For the longest I couldn't figure it out. What the hell does tacos have to do with hockey? I finally realized that the taco place that sponsors the team gives out free tacos if the team scores a certain amount of goals per game. So instead of chanting for the team to score they chant that they want tacos. Weird.
Oh good, I thought I was right. I might turn this game off soon. Shits fcked up. Think I'm gonna have to think about life after a Super Bowl loss.
In my hometown the local football team used to chant 'Ricky Herbert's (the coach) Yellow Army!' But I heard 'Come on, mate!' for the longest time.
