It's not the size of the stripper, it's the motion of her ass while werkin' it for Jadakiss that counts ... if you're a tiny stripper in a West Virginia club.
It all went down after Jadakiss' recent appearance at Lust Gentlemen's Club. We're told the little lady -- she goes by Ivy -- surprised the rapper in the VIP room after his 30 minute set.
You gotta see her moves, and especially Jadakiss' reaction to 'em.
We're told he made it rain $300 for the private dance. Money well spent.
