Michael's Crotch Dance

Them dancers, singers there on MTV, why do they grab their crotches frequently? I've tried, but I still can't figure it out just what on earth that dance move's all about. That crotch-clutching flick of a mannequin must be a part of hip-hop hand routine with nothing there that's meant to be obscene, but which these prudish eyes just now have seen. But then if it's because of poor hygiene, it's time to see the doc, to check what's in between; if they won't wash and scrub themselves real clean, like chimps with lice, they'll scratch, they'll make a scene. But sure, they know too well what should be done: if they don't scrape the itch, it will be gone; well, Michael Jackson, dance king of all climes, at fifty, clutches still his crotch fifty times!
