I'd imagine this is pretty common these days, but students at DW Daniel High School in Central, South Carolina had to sign a contract in order to attend their Winter Semiformal and Prom dance. Along with agreeing to a no-drug/alcohol policy and dress code (nothing see-through, no ball caps, no low-cut dresses, must wear shirts, etc.), they must abide by the following "Dancing guidelines (applies to dancing on and off the dance floor)":
No straddling legsAlso, no Elvis the Pelvis shall be played. OK, I'm kidding about that. I think. (Thanks, Steve Marks!)
No bending over while dancing
No front to back grinding
No "making out" (no overt and/or prolonged public displays of affection)
No crowd surfing
Hands on waists or shoulders
