The act of, while having sexual intercourse with a female in the doggystyle position, grasping a nice firm hold of the said womans pig tails, and slipping out of her vagina and penetrating her anus. She will "roar" and attempt to escape your man-meat, but the trick is to maintain control.

NB: Can be done with two men however this is seldom seen.
