Something I've often wondered about -

There's a "dance move" in several Bowie videos where he or someone in the video bends down and touches the ground with their right hand. Do you all know what I'm talking about? I can't describe it well.

Anyway, I've wondered, does this move have some sort of meaning behind it? To me, it seems like this means something. Does anyone know anything about this?

Don't look at the carpet, I drew something awful on it
