Actually, I think what Chuck Berry does across the stage is called a 'duckwalk'.

Duck walk - comes from a skating term - meaning - to transfer weight from the toe to the heel whilst walking.
Maybe the detective had the guy cuffed and hoisted hin up so that he had to walk in a toe-heel manner. In BrE we call this "frog-marching"
