Moonhouse 

Synonym for outhouse.

Term exists because many old outhouses have a moon carved into the door.

That moonhouse by the highway smells like shit.

Montana Moonhouse 

Two people are going at it in an outhouse, the man standing, and the woman bent over. Either while or after the man climaxes, he shoves the woman's head into the septic pit.
Similar to a swirly, only instead of a semi-clean flushing toilet, they just get lots of feces all over their head.

Jana's hair sure smells shitty since the Montana Moonhouse.
