Hello, friend. If you've arrived at this definition, then you don't know how to spell
poop chute. That's okay; it's a common error. People often become confused because shoot and
chute are
homophones. In addition, the idea of one's butt as "poop shoot" does make sense on some level if one imagines the asshole as a sort of gun that shoots poop as a projectile. This sort of thinking, however, is misguided. In actual fact, the imagery from which this slang term is derived envisions one's butthole as a chute from which poop is discarded.
