I was at the two games Wisconsin played in Omaha, there was some of that from the home fans near us. It took a bit, but I figured out in the 2nd what they were saying. If my 7yr old had figured it out, or asked me what they were yelling, we'd have been out of there.
As it was, I texted the "unruly fan" number they had posted, and somebody came after a while.
