I've seen bad fans from both schools at every college game that I've been to. Same goes for the good fans, which have far out numbered the bad ones.
Usually there is some beer or booze involved when some get out of hand or go over board. Some people are just a-holes.

As a big SOONER fan I'll say sorry to LSU fan for the rudeness that you were subjected to at the National Championship Game and Congrats for winning. It still pisses me off that USC claims to have won the NC.
