Dear, what you want to say is a form of performance called "flash dance", commonly known as flash dance, and some people say it was Michael Jackson's. At first, many dancers dressed as passers-by walked around the streets or public places at will. They were killed by listening to music and dancing by themselves. The music came to my mind for a while, and my friends suddenly took off their clothes outside, and then danced to the music, just like dancing at the airport when I was a girl. After the jump, they all became passers-by!
