6-2-1 rule is a 2023 wellness trend prescribing specific daily ratios for sleep, exercise, and other habits. Various versions exist. Not particularly concerning, generally promotes balance. If your kid uses it constantly, ask them where they first heard it, not to police their speech but to understand which online community they are in. Most slang of this kind moves through TikTok and group chats, so seeing it in your child's vocabulary just means they are plugged into normal teen internet culture.

For ESL learners
6-2-1 rule is a 2023 wellness vocabulary phrase referring to various structured daily routines (different specific versions exist). Use in wellness writing. Formal equivalent: "a structured daily routine." Common non-native mistake: assuming a single definitive rule; multiple 6-2-1 frameworks exist (sleep ratios, fitness routines, productivity schedules). Always specify which version. Read or listen to the word in context several times before trying it yourself; the right register is harder to learn than the dictionary meaning.
