Twerking has no place on school grounds.

That’s the sentiment at River Ridge High School in Lacey, Washington.

The school has handed out contracts to students and parents, in which the kids agree not to perform any risqué dance moves or “look like you’re having sex” while at a school event.

The contract forbids students from giving lap dances, bending 45 degrees or getting on the floor.

Students who violate the agreement receive a warning the first time and repeat offenders run the risk of being banned from future school events.

A spokesman for the school district said, “Kids express themselves differently these days. All you have to do is turn on YouTube and see Miley Cyrus. And we just want them to know that at a school dance there's certain expectations about how you dance.”
