What do they mean when they say, "Walk on the side" at Junkanoo?

Does that mean to do the junkanoo one-two shuffle on the side of the foot 'cause the costume is heavy?

No one?

I just heard someone say that yesterday. I asked what it means and the said das old people talk. One person was telling us bye and the other person who was there said to him "Hey, walk on the side hear."
