this is one of my favorite club songs out right now.
When you grow up as an American teenage, we're blessed with really good music makers which spawn really cool dances. This song really makes me miss doing the Cabbage Patch and Rodger Rabbit dances when I was kid from the 80's.
In every generation, it seems the coolest kids come up with these crazy dances that reflect the times.
The Cabbage Patch was based on the Cabbage Patch doll and the Rodger Rabbit was based on the cartoon from the movie.
So these young rap guys are talking about, "Teach me how to Dougie" , your guess is as good as mine.
