Cant really give a definition, more like a story. So your fucking a girl and you have no condom and you dont feel like getting her pregnant so what do ya do? Poopshutemagoo!
This is often compared to an ass hole or a butt hole, it is where the poop exits your body, or if your really mad or drunk you can call someone a poop schute, and it can be very offensive
You found a definition mentioning this word um what is it? It is something you use to eat out your dog's ass after it had worms.

After girls poop, if there's a piece still stuck in there that can't be pushed out, she can put her fingers in her vagina and push up into her colon and it'll come out.
Janie had a piece of shit that wouldn't come out so she gave herself the old two-fingered poopchute and out it came!
