Twerknado: Kenzie Madison. Twerknado is a series named after Kenzie Madison because of the signature way she can throw her ass around and make it move in a circle as she rides quickly up and down. We'd never seen anything like it before, and we haven't seen anything like it since. We started this Twerknado series because of Kenzie, but she will always hold a special place in our hearts, as will this scene because it's the last scene we shot in Seattle..
