Also referred to as ITBES, this is a serious psychological disorder. It doesn't really matter if you catch it early on or not, as unfortunately, there is no cure. Common symptoms include, but are not limited to:

- Irritability when passing a Taco Bell and not purchasing a Taco Bell product.
- Craving Taco Bell 24/7.
- Trying to make a Taco Bell substitute at home. When the chef with ITBES fails, he or she will throw the taco creation at the wall, screaming "THIS WILL NEVER BE GOOD ENOUGH! I NEED TACO BELL NOW!" (or a variation of this phrase).
