So my LSA91 wife and I went to our first Big House game in a few years, and saw many things that impressed our creaky minds. Some were pretty self-explanatory and fun, like walking in behind the band, seeing a full student section (through the third quarter anyway), or watching the team demolish an opponent.
I'd love some more background on a few of the others - where they came from, etc. I tried googling, but I'm old. Can someone point me to a good page discussing or explain:
1) The third down chop/wiggle/"you suck" call. (Yes, self explanatory, but where did it come from and when.)
2) The student dance. (Same thing).
3) About 10% of the girls walking to the game were just about half-way to a halloween costume - typically knee socks and a night shirt or short shorts, but there were some cheer costumes, shiny skirts, etc. Is that a thing every game, and is it in college sports generally or just AA?
