Definition: The word '2303' is a blend of euphemisms and profanity that's used to describe the chemical compound known as phenol. It's a colorless, odorless, tasteless, impure substance that occurs naturally in plants, algae, and some bacteria.
Imagine it like this: You're at home with your parents and you have a little bit of fun. They're not expecting much, but they secretly want to know the chemical compound you just used in front of their face. So, '2303' is like that little secret that's inside your mouth - it's not really real or something you've ever seen before. But it makes them feel a bit more comfortable and curious about what it tastes like when they actually drink it.
