It's like vomit from your asshole.
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.
Diarrhea is gross, but everyone has it.

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.

Loud, smelly, and it hurts.

just like Scientology.
guy: i was walking to my next class when i felt the urge to fart, i aimed my ass towards an open locker and farted while pretending to investigate my pencil. i felt my underwear and ass cheecks fill with a warm liquid, i was terrified, i thought maybe i should run to the bathroom but i realized that would be too obvious because diarrhea would go flying everywhere and everyone would know it was me, so i thought quickly, I grabbed a blind kid and had him walk directly behind me as i lead him to the bathroom telling him id give him candy, i got to the bathroom and had the blind kid lay in front of the door to make sure no one came in and cleaned myself up. disgusting day tbh.

A fiery liquid shit that comes out of your anus at a very fast pace to allow you to melt any solid object in a matter of miliseconds. If applied to a liquid, it'll cause the vapor to fuck you in the ass and make you fat.

Suggestion: Stay away from taco bell.
