The act of a male extracting feces on the females chest between her breasts, and resuming to have intercourse of his penis in her breasts. The mess caused by the spreading of feces by the male penis results in a scene resembling a mudslide on the hill that is the woman's breasts.
Man, I really gave Amanda a crazy Alaskan Mudslide last night. Some of that "mud" got smeared all over her body after I laid down some textbook heavy artillery thundercock.
