Machu
A Machu is when you have anal sex with a Peruvian woman, but you forget to clean her, and when you pull out, she lets out a massive colon blow that covers your whole Johnson like a surprise party.
He had a Machu and it was like a surprise party on his Johnson.
She let out a colon blow so big, it could be heard from the next town.
He didn’t clean her, and now his Johnson smelled like a garbage dump.
