Mexican Brownie
The sexual act of of a man sitting in the "taking a shit" position while a woman waits below to capture the feces inside her vagina. If loose enough, a loud "sploosh" should be heard upon impact inside the woman's vagina. It should be known that absolutely no pleasure from this occurs and could probably have some severe health defects, but hey, that isn't going to stop you from trying it right?
-Hey man I want to give that girl a Mexican Brownie.
-Why because she's homeless?
-Nah, because her twat is hanging off the floor.
