I'm not sure why people come up with specific dances and stuff, and I'm really not sure why anyone studies said dances (not that I'm considering the Harlem Shake to be a dance, mind you, I'm talking dances in general). If I start dancing, I'm certainly not going to be copying some fool who made a music video. I have two dances, they're very similar, but one is designed to maximize female attraction, and the other is for sending a clear message to other males that I will eat them alive. Because both are so similar, it's easy to switch it up and let the whole club know who's in charge; this wouldn't be possible with some other person's dance...then I'd just look like a bitch.
