I disagree that dry humping on the dance floor is not sexually charged. If my sixteen-year-old sister is any indication, everything they do is sexually charged. And far from innocently so. For many of those kids, the grinding likely is a prelude to the sex they’ll have at the after party.
Trying to teach the kids some swing or salsa moves before the dance probably wouldn’t work unless the popular kids decide to think it’s cool. Plus, dry humping requires very little skill or concentration - it’s something people who can’t dance can do without a problem.
Chicken noodle soup? I’ll be staying up nights to perfect that one.
