A Shuttleworth - A person who takes the biggest poops in the history of poop.

A person who takes the biggest poops in the history of poop. It can punch through concrete and make you go insane

I was in the hallway and heard a Shuttleworth and I got a headache and started crying

My neighbor took one and the whole building shook and I got a rash

My dog took a Shuttleworth and now he can’t stop scratching and he’s rocking in circles
