Dramatic movement of a small sign by someone hired to attract motorists to a specific place of business. The best sign twirlers are very flamboyant and really grab your attention.
I went to the new restaurant's grand opening only because of the outstanding sign twirling at the intersection.
A female who dresses slutty and acts slutty while twirling her hair who throws herself at anyone that looks at her and desn't care if the person is married.
to one friend " I saw so and so's husband taking some hair twirling slut into a cheap hotel"
