Well, I'll have to say that my high school experience was a lot more PG than that. On the "behind the scenes" bit on the DVD, all of the young actors were talking about how realistic it was, based on their high school experience. That could be, I wouldn't know. Maybe it was because I went to a Lutheran high school. Maybe it was because I was one of the geeky kids. (Yes, I did go to band camp. No, I do not play the flute.)
One thing I did get out of the movie was prom, and the fact that I never went to one. My school didn't have one. Every year, a group of the rich, popular seniors would organize one somewhere, but it was always an expensive, private affair. What everyone else had was "Junior-Senior Farewell", a dance that was free to all juniors and senior (but no guests) and somewhat casual as far as dress went. I've never worn a formal (other than trying one on at a store for fun) and I've never had a date in a tux. Bummer, eh?
Still, even if the high school that I remember was nothing like the high school of TV and the movies (thank heavens it was nothing like Sunnydale High!), my memories of it are mostly fond. I certainly wouldn't want to have to do it again, and I've lost touch with all but a small few of my high school buddies, but the nostalgia is definitely there.
