A form of anal intercourse in which the male partner vigorously fucks his female counterpart until she begins to bleed, at which point he gives her a Mike Tyson directly to the lower abdomen. Usually causes uncontrollable shitting by the female; in rare cases, she may even go through anal prolapse.
I just cocked my fist back and gave her a straight right hook to the stomach. What a Muddy River.
