Similar to projectile vomit, except from the anus. Normally explosive diarrhea is bile and orange juice, accompanied by chunks of scratchy objects ranging in size from a pebble to however big your ass can stretch, and unexpected volumes of fart which do a marvelous job of dispersing said liquid and chunks. Explosive diarrhea is deceptive; leaving the top of the lid virtually unharmed, yet devastating the underside.
Someone had explosive diarrhea at ihop

A mostly liquid rectal discharge of significant force and velocity resulting in fetid splatter throughout the interior of the toilet bowl, almost always accompanied by an intensely foul, gaseous emission caused by the violent release of putrified colonic gas. The relief from bowel pressure experienced after such an assplosion is usually offset by the burning sensation of anal itching known in the vernacular as the "Ring of Fire."

To have diarrhea that is so compact and air tight in your anal cavity, that as soon is your buns touch the seat, your asshole explodes like a 12-gauge shotgun and you can hear the cries of 1000 virgins as the shit flies from your ass.
