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.
