Depends on what you mean.
According to urbandictionary.com:
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.
Petite SPs in E-town I would recommend are Brooke at Cloud Nine and Zoe at Prestige. Neither has actually done the spin...at least not with me. The only SP I knew who performed that feat was Maria at Cloud Nine, who disappeared from the scene a couple of years ago.
