If you’ve been anywhere near a school lately, you’ve probably heard the phrase “6-7” tossed around like it’s the secret code to coolness. Teachers are baffled, parents are Googling, and kids are just smirking. Nobody seems totally sure what it means — and that’s exactly the point.
Like every great inside joke of youth culture, 6-7 has gone from playground whisper to full-blown nationwide phenomenon faster than you can say “mid-sentence eye roll.” One minute you’re hearing it at recess, the next it’s trending on TikTok and showing up on hoodies.
😎 So what is 6-7, anyway?
Ask ten kids, you’ll get ten answers — which is what makes it brilliant. Some say it’s a comeback. Some say it’s a rating. Others say it’s just a vibe. Whatever it is, it’s become the unofficial language of “you wouldn’t get it, Mom.”
And honestly? We love that energy.
