When a woman gets on her knees and angles herself to where her head is up higher than her butt. A man with diarrhea shall go to the top of her body just below her head, and poop out his fecal matter onto her back. As it slides down her back and off her butt cheeks, it look's like a California mudslide.
The process which involves engaging in anal sex, and your female partner defficates on your penis, you then proceed to insert the penis in the vagina with long hard thrusts getting all the feces off the penis and into the vagina. Next, you get a standard size Turkey Baster and proceed to insert 4 to 6 cups of water into the shit filled vagina, shake your female partner around while holding the labia together and then finally have your female partner squat all over your head spewing out shit and water on your face resembling a California Mudslide!!!
