I would have to say that when I am at the dance studio I never twirl nor does my partner. We turn, we spin, we spiral, and that sort of thing. But we don't twirl. I never tell anyone to "break a leg". That would be like the worst thing to happen to someone who dances and it is no laughing matter. I wouldn't take it personally if someone said it but it is just something I don't say. I don't tend to do "some moves". I dance. I do steps. I practice techniques. But I don't just do some moves. Are there any other words or phrases that come to mind that you really don't use at the dance studio but you here the general public use?
