The act in which the male or female with a strap on, points the shaft upwards vertically while lying down. The partner, male or female, then proceeds to "sit" on the shaft - with it in the anus. Then while the person lying down stays still, the person riding the shaft proceeds to spin around almost in a breakdance type fashion. Except this time while the partner spins around on the shaft, they defecate and liquid shite is spread all over the partner's scrotum and abdomen.
