From Classrooms to Culture — Why It Works

While TikTok users found “6-7” hilarious, teachers weren’t quite as amused. Educator and creator Mr. Lindsay explained that the phrase carries no hidden meaning — it’s just a meme that spread because it’s fun to say.

But in classrooms, that harmless humor quickly turned chaotic. Another teacher, Kaitlyn Biernacki, said students began blurting out “six!” followed by “6-7!” in the middle of math lessons. Others would chant it during counting exercises, forcing some schools to quietly discourage its use.

Even so, the “6-7” craze says a lot about how fast digital culture evolves — and how younger generations constantly reshape humor. To many adults, it’s nonsense. To kids online, it’s comedy gold.

In the end, that’s the whole point. “6-7” doesn’t mean anything — it’s simply a shared wink between millions of users, a reminder that internet humor doesn’t always need logic to make people laugh.
