BRIGHTON, Mich., March 25 (UPI) -- High school students in Brighton, Mich., say they'll boycott a prom because they've been asked to sign contracts against "freaking," a style of dancing. "We're not trying to have sex on the dance floor. We're just trying to have a good time," senior Josh Partridge said. Various Detroit-area schools have tried to deal with freaking, in which dancers mimic a sex act as they rub against each other, the Detroit News said Thursday.
