Hiroshima'd

A large amount of excreted waste, possibly toxic.

When you come home after eating the whole taco bell menu, and you hear a loud grumble. You struggle to get up and you trip getting to the toilet. It's too much for the toilet, or even the bathtub. You have no choice but to find the biggest area to use as your new septic tank. You just Hiroshima'd all over the walls.
