"Spinner"https://www.urbandictionary.com/define.php?term=spinnerA petite woman. Denoted as a joke, whereby the petite woman is so thin she is able to be mounted and spun in a circle on an erect penis.
"She's a spinner."
A term I've heard for close to 20 years, and I always had a vague idea what it means, but here it is defined. It's one of the few terms I've not been able to find on either Wikipedia or Dictionary.com
Because it is, quite obviously, crude slang. And not even that clearly defined.
