There are whistlers at Vandy basketball games. Most definitely at the women's games, where the crowd's not always as large so they come across extra-clear and extra-annoying.
And speaking of being clear, the Whistler is not a "ha ha" funny thing. It's a "I'm a hardcore piece of crap who's going to ruin this for everyone but me" thing. Screw 'em. I couldn't imagine making it more than one quarter sitting near them before I'd resort to action. "What does action mean?" I don't know, I only know I'd have to explain it to a judge.
