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.
Look at this chick walking down the street. As soon as I drove up, she started switching. She still ain't gettin' no ride. I gotta get over my mom's for some of her bomb ass potato salad.

Most commonly used as a term to negatively express the passing of time with extreme inactivity or waiting. Very similar to the term "Grab Ass".
