Pretty trashy but nothing compared to HS kids. I take pics during my son's HS games and mostly live on the visitors sideline. I have literally been called any thing and everything. I'm mid 40's White guy with a receding hairline and I've somehow been "mistaken" for every race by every race and called all of the forbidden racial words. I've been confused with genitalia, and body functions, they've call my son everything in the book so I stopped wearing a shirt with his number on it.
At a handful of the UT home games I've attended, I've sat near the student section a few times and heard things that would make sailors blush. Again not condoning it but football is a heated sport with a lot of emotions, alcohol and bad judgement involved.
The thing that I've heard that stuck with me the most was a pretty highly rated player running of the sideline after scoring calling my sons team pu$$i3$ and chest bumping one of the coaches as coach bro responded "you know what we do to pu$$i3$ we pound them."
