Rumor has it the "Birdwalk" dance may not really be a dance created by Soulja Boy. It is believed that Soulja Boy stole the dance from a artist by the name of Tocka out of Cincinnati. The original title of the dance is said to be called "Down The Way" It is also said that the dance has been really big in Cincinnati for quite a few years now.
In my opinion it really doesn't matter who created the idiot dance because I never liked it in the beginning. Check out the video below of the so call "originators" of the dance.
