Fed up with students' racy moves, a principal at a California high school has taken the unusual step of canceling the rest of this year's school dances.

Principal Jim Bennett of Lemoore Union High School (search) said he warned students at a winter formal dance last month to either quit dirty dancing or face the possibility of not dancing at all.

But he said the students continued "freak dancing," (search) a form of sexually suggestive dancing that involves grinding the hips and pelvic area.

The ban on dances includes the school's Sadie Hawkins dance in February and the junior and senior proms in the spring, but Bennett said they could be rescheduled if students modify their behavior.

"It's really up to the kids at this point. They have to take some responsibility," Bennett said.

Organizers of the Sadie Hawkins dance, a fund-raiser for the school's Future Farmers of America (search), are working with Bennett to come up with a series of regulations, which could allow that dance to go on.

One idea is to let students sign a form stating that raunchy dancing will get them kicked out.

Students hope similar regulations could lead to the reinstatement of other dances, particularly the prom.

"Some students save up all year to buy a dress or rent a tuxedo and buy flowers for the prom," said student body president Zohra Lakhani, a 17-year-old senior. "To crush everyone's dreams, it's not fair."
