Yesterday I saw it used in 2 reviews. In one,that I rejected for being too short, the reviewer called his dancer a spinner and then went on to describe her huge rack.
The other mentioned a dancer by name at my favorite club and called her a spinner. She is not over weight but is no spinner.
I borrowed this from Urbandictionary:
"A 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"


The glossary is out of date and does not cover many common terms (like "spinner"). I think TUSCL members (or at least VIP members) should be able to add words and definitions.
