Everybody has already said that dance in whichever way you like, so I don't have to repeat that (well ooops, I kind of did).
I like to watch goa/psy people dancing for all the expressive, liberated moves. :posford:
The funniest dancing I ever saw was at a techno/house party like 8-9 years ago. The guy looked like he was collapsing time after time and I mean vertically, not falling over to side like a cut tree. It's hard to describe, but it looked so funny. I actually had a chat with him at some point that night.
