You have a helluva daughter if she can synthesize what a crowd is screaming, and if she does and said it in school, everyone would just laugh and know she went to an LSU game. We always joke about how when I was a kid I supposedly got Jimmy Buffett's "why don't we get drunk and screw" stuck in my head. Does that make my parents bad parents? That stuff just happens, ya laugh about it, and move on.
I understand that Louisiana people are different than most folks. As someone who grew up there and then moved to Clemson, I noticed it immediately. People in Louisiana are probably a bit trashier in theory than others. Their jokes might be a bit more vulgar than others, but I'll be damned if I've ever met someone from Louisiana who doesn't have a good sense of humor or who doesn't know how to have a good time.
There's a lot about this state that could be considered trashy or dirty. Hell most aspects of Mardi Gras are exactly that, but they're damn good people all around and I think a lot of other folks just need to lighten up. Again, it takes all types so I'm not saying there's anything wrong with that, but I found South Carolina folks on the whole to be a bit more formal and reserved than Louisiana people. That's fine, but I found it to be a bit boring.
