"I need my fix, give me a twenty." *Plop* "You know what you have to do bitch. Start BLOWING MUD HOE!"

Mud Blowing 

The act of spitting the poo that your partner unexpectedly deposited in your mouth during a rim job (analingus) back in his mouth. Some people may like this, but, in general, it is thought to be an act used to get back at a guy for pooing in your mouth without warning.

Allison: Mid-rim job, he pooped in my mouth without any warning, so I decided mud blowing was the best way to get the punk back.

Katherine: He shouldn't have at that second Fiber One bar...
