The 6-7 meme is pretty widespread at this point. It is Dictionary.com's 2025 Word of the Year despite containing not a single letter, and it is a source of both entertainment and irritation among my own kids as well as every teacher I know (and parents too).
With that in mind, follow me down a historical 6-7 rabbit hole. Is there a connection? 🤔
