Firecracker shotgun

When your sitting on the toilet (preferably after a heavy night of drinking) where you have diarrhea, you fart at precisely the exact moment the shit deploys from the anus. Also occurring is a noise quit similar to a firecracker while the fart exits the eye. Its starts off with very loud flatulence which occurs due to the flutter of the cheeks. It quickly turns into a whistle like sound while slowly increasing in pitch. After a brief moment of silence it ends with one more powerful blast of wind exiting the rectum. All this happens in approximately 2 seconds. Since the explosion exits the bowels so quickly, the fast contraction of the anus leaves one with a burning sensation that can only be relieved by sitting on the toilet for a few minutes with out movement.
