Machu Picchu
When you're giving a Peruvian woman a good time in the back, but you forgot to wipe your butt, and when you pull out, she lets out the biggest poop ever on your junk.
My uncle told me he got a colon blow so big, it smelled like a garbage truck.
My friend said his Peruvian lady friend hit him with a 'poop explosion' and he couldn't walk for a week.
He said he got so much poop on his junk, he had to take a shower in the middle of the street.
