man butt baby

When fecal matter and sperm mix, usually the byproduct of when a man ejaculates into another man's rectum via the anus canal. This is considered a gay sex act in certain circles.

In typical heterosexual relationships, a man's sperm usually fertilizes the women's eggs via vaginal intercourse. When it comes to making a "man butt baby," the egg is replaced with what is colloquially known as a turd.

"Taking a dump" or evacuating one's bowels after engaging in said act is also known as "delivering a man butt baby."

Mudd Butt

The end result of clenching your butt cheeks together on a turtle head making it's way outside of your ass. This especially happens when you're short on film time and can't take a break to take a giant dump, and always requires wet-wipes to completely wipe yourself clean.
