What does it mean when an escort saids she is a spinner?

"Spinner" (Adjective - Slang) Used among some men to describe an extremely petite young woman, usually with a lot of sex appeal - the term is thought to reference the small stature and weight of the woman; (IE she is so petite she could be spun around while riding the man during sex). Ex: Man #1- "Aw man, look at that girl, she's so tiny." Man #2- "yeah, she's a spinner."
