Definition

Gen-Z slang for someone born in 2004, used to establish generational street cred and age-based hierarchy within friend groups. It's particularly relevant for those awkward edge cases where birth month determines which school year you're in. Basically, it's the year-based version of astrology for teenagers.

Example Usage

"Wait, you're an 04 baby but you're in our grade? Oh right, you must be a late birthday."
