Ninja Shart

The act of releasing a ninja fart, but you also shit your pants without making a sound. It is a disgusting and the most foul smell and completely silent. They usually smell like a bag full of diapers tossed into a tire fire. The Ninja Shart also shows no reaction by the flatulent bastard. A silent but deadly Shart! Basically a nuclear bomb of crop dusting innocent bystanders, and shitting your pants while no one hears a thing.
