Gasturd 

A small turd lingering within a huge fart. You don't know it is there. When you let it fly a gasturd can be propelled at a rate speed beyond that in which a bullet exits a gun.
When a gasturd hits the water, your ass gets soaked, similarly to sitting in the Splash Zone at the Shamu show.

A gasturd has the greatest 'size to impact' ratio of any object known to man.

A gasturd may easily be mistaken as a shart, so please remember a gasturd exists within a fart and is not a mistaken fart.

"Wholly shit, what was that. I thought it was only a fart, but it was a gasturd. It shattered the toiletbowl and I am soaked."
