A white girl with a pancake butt who, while attempting to grind/get freaky with a guy, is unsuccessful and instead creates a side to side motion that does not create any pleasure for either partner. In fact, swayers can be known to cause seasickness and extreme boredom.
"Man, that danced fucking sucked! Every girl I danced with was a swayer!"

A girl that goes from one guy to another. She doesn't date any one guy and she just hooks up with different guys.
That girl is such a swayer. I heard she hooked up with one guy last week and last night she hooked up with another guy.
