Used when someone refers to an idiot who says stupid shit every time they talk.
Can also be referred to in context of the Southpark episode where Cartman demonstrates how to eat with your butt and poop out your mouth, literally.
You need to stop talking. It's like you poop out your mouth every time you open it.
You see that episode of Southpark where Cartman pooped out of his mouth?
