Call me a noob but I don't get what the video implies.

Around 1995 in Louisiana the original booty shaking dance was referred to as PR dance meaning Pink Rack. It got it's name when a famous African-American dancer was first seen performing the dance in the Jazz Halls wearing the popular at the time dress style which also happened to be Pink. The name can still be heard during the Mardi-Gras in certain parts of the city. /some BS I just came up with
