Muddy Garden Hose
When a man inserts his penis into a girls butt and she shits on his penis, then they both thrust together in a way that pushes the shit into the mans urethra. The man then urinates the shit out of his penis into the girls mouth while shes sucks it.
"I tried giving Ashley a muddy garden hose last night, but now it hurts when I pee and she wont talk to me anymore."
