What the hell is the stanky leg?

As I turn on the radio and flip through the local hip hop stations, "Do the Stanky Leg" comes on. Really? The stanky leg? Lately, rap songs have come out complimented with dance. There is Soulja Boy's "Crank That", B Hamp's "Ricky Bobby", Dem Franchise Boyz "Lean Wit it Rock Wit it" and many more. It just awes me on what sells. The lyrics for these songs are absolutely ridiculous and many times have no defiant meaning. However, with catchy beats and fun dance moves, these types of songs have become overwhelming in our society today. But seriously, what the hell is the stanky leg? It baffles me that so many uneducated hip hop stars come up with these songs that everyone pays to listen to. Well, bitch I'm wild up! Do the stanky leg!
