Taco Bell

Taco Bell is the name of a chain of fast-food taco, nacho, and burrito-serving restaurants, that is paired up with KFC. The joke about Taco Bell (and pretty much all taco restaurants) is that it makes people fart a lot, get diaria, or poop immediately after eating it. Taco Bell is a common topic in Bathroom Jokes, and bathroom (or bathroom-ish) memes, especially using the Bathroom After Taco Bell joke.
