A smelly substance that torpedos out of ones asshole. Reaching speeds of over 90 miles an hour. Diarrhea can come in a variety of colors and is always in a liquid state.

10 slices of pepperoni pizza, 4 pieces of chicken, 2 cups of kool aid and I was expecting a huge weight gain. All I got was diarrhea!

I tried to engage my butt's gag reflex with a finger. I soon discovered my anus wasn't truly a mouth and the only common trait shared was regurgitation. Diarrheal carnage ensued.

Smelly runny juicy stuff that comes out of your anus. Fills up your toilet with runny remains and burns your asshole. Makes noises when comes out of your butt, like a squirty sound. Stinks up the bathroom and makes you gag when you wipe.

The stunningly painful feeling McDonalds spent years of research looking for a way to trigger. It'll get you as soon as you're finished eating and try getting up.
If you have a long road ahead of you after you get out of McDonalds, you'd better use the toilet before you leave, or you'll be painfully holding your diarrhea until you arrive home. Especially if there's blizzard outside, forcing you to slow down, and it's too late to stop anywhere.
