Yes, I know all about Yanis Marshall. He's the one who popularized Heels classes. Marissa Heart is another good one to watch for a similar style:

The point is you are not going to dance like that in a club. It's choreography for a reason. I could also point out Vogue Fem, Burlesque, and myriads other styles. What you and others were talking about is casual social dancing. And when it comes to that, both girls and guys are just randomly flinging things and bouncing up and down. Unless they are flirting or just trying to be funny they are not full out shaking their boobs, hips, butt, etc.
Well, have fun whatever you do.
