Cheerleaders

From Frikipedia

In America, cheerleading is a way for women to leave their mark on the male-dominated sporting arena, by participating in the age old ways of dressing in lycra and doing the splits. With pom poms. Currently, there is a vicious debate raging between cheerleaders and actual female athletes over whether or not cheerleading should be considered a sport. There are a few male cheerleaders, but they're generally beaten up daily by jocks. And their female counterparts.

In the UK, cheerleaders tend to be local butterfaces, and most routines are choreographed to the point of them being almost in time.
