“The principal of a south Orange County high school has lifted a nearly three-month-long dancing ban he instituted after seeing teenagers’ sexually suggestive moves at school dances that were ‘one step from events that should be occurring on wedding nights.’ … The new guidelines forbid students from straddling each other’s legs, bending over, dancing front-to-back, grinding, touching breasts, buttocks or genitals, or ‘making out,’ and require students to keep both feet on the floor. The guidelines also limit dancers’ hands to their partner’s waist or shoulders.”
