A urban myth of a haunted being observing people as they engage in excretion. It is said that it is the reason for most discomforts during bowel movement and paranormal activities when one is on the loo, such as odd noises from the outside. It is said that the poop ghost can only be prevented by the presence of boobs near the person pooping, either physically or visually.
1: I couldn't let it out, I got way too scared to poop in the bathroom.
2: It's probably because the poop ghost was bothered by you.
