This influential style of dancing was made popular in the 1920's, and was considered by some to be the height of decadence. It mainly consists of awkwardly flailing one's arms and possibly one's legs in a bizarre manner. There has been nothing so easy for those of the Caucasian persuasion as this dance. No wonder they say white people can't dance. It's not that we can't dance, its that the styles of the times have progressed beyond the maximum skill of white people.
In conclusion: The times may change, but white people dancing still sucks.
