When things just really really suck and your having a crappy time.

When you sit down to shit and your crap comes out faster than you can control, and you spray poop all over like a fine mist.

I drank a fifth of gin, and ate at Taco Bell today. Tonight the forecast calls for one huge Fecal blizzard.
