An older (70s-80s) term that means to walk in an exaggerated motion, where you are rocking, or "switching" your behind back and forth to get attention.
Streetwalkers do this to get the attention of
johns. Therefore, switching is not seen as a positive term. It's a term used for someone who is considered slutty, promiscuous or just a plain
showoff. Usually used for women but also sometimes for effeminate or gay men.
