At BYU, we'll get chewed out by a random fan if we yell "air ball" at the other team because it's "mean" and "we're BYU so we have to represent the church..." (My group of friends decided it's a 1/5 ratio... 1 out of every 5 games we get chewed out by someone random who probably hasn't ever gone to a game before. Goes up to about 3/4 if Brian Santiago is sitting near us).
The worst Utah fans will cyber bully #BYUPat with 3,000 tweets and dump beer on people.
I don't know which is more annoying, we have similar amounts of annoying fans, but they are opposite ends of the spectrum.
