Warning: The following standards are not actually standards. They're just a bunch of made-up rules to make you look cool at taco parties.
Rule 1: Always add a sprinkle of queso to your taco. If you don't, you're a monster.
Rule 2: Tacos must be eaten while standing, or risk being considered a basic human being.
Rule 3: The only acceptable topping is carne asada. Don't even think about it, you'll regret the thought.
