When your bowels and your sphincter spasm while your are having the runs, the fecal matter "explodes" out of your ass causing a mess that will make you wipe for at least a half hour. Makes a nasty yet very funny sound when it echoes off of a toilet bowl. Can be thought of as throwing mud, but that is just a small amount usually and it is done in your shorts.

In Jhonen Vasquez's comic, Johnny the Homicidal Maniac, the main character 'Nny visits Heaven, having beeen denied entry into Hell. While in Heaven, 'Nny learns that, like all behind the pearly gates, the ability to explode people's heads has been conferred upon him. Very messy antics ensue, preceeded by an exclamation and a blood-thirsty grin, "I have Head Explody?!"
