But he didn't steal the dance from anybody. I know you are from Germany, so I can't expect you to understand some things. But if you are apart of the culture and from the same hood, you can't steal from it. In hip-hop things feed on themselves in a way. So if one guy makes up a new term/word, then the neighborhood starts to use it, then the whole city starts to use it, and finally, a rapper starts to use it. If that word gets crazy popular within the world 2 years later, the rapper from that city gets the credit for it's "creation".
