Dancer Jargon?

Hi there, I'm back.

So, during Elayn's class tonight, the topic of Second Life dancer jargon came up.

Jargon (n) the technical terminology or characteristic idiom of a special activity or group

The first term that came up was "Ball Warmer." I believe that refers to someone who just puts on a costume and rides a mover as a dancer, doing nothing else.

What are some other terms that we use in dance?

Put them in the comments.
