Why 67 Took Over The World

A throwaway lyric became Word of the Year — and the reason why is older than the internet.

A teacher banned a number in 2025. Not a slur, not a swear — the number sixty-seven. Say “six-seven” in certain classrooms and a room full of kids erupts as if you’d delivered the greatest punchline of all time.

By the end of that year, that same meaningless number was crowned Word of the Year by Dictionary.com — a word that, by their own admission, isn’t really a word and doesn’t really mean anything. The reason why “67” went viral isn’t randomness. It’s one of the oldest patterns in human behavior.

And once you see it, you can’t unsee it.

Where “67” actually came from

The trail starts with a Philadelphia drill rapper named Skrilla. His 2024 track “Doot Doot” includes the line “six-seven, I just bipped right on the highway.” Skrilla has said the meaning is intentionally vague. There was no hidden message. There was barely a meaning at all.

Then the internet found it.

• In early 2025, TikTok creators synced the snippet to basketball edits — “six-seven” doubles as a famous height, the 6'7" (2.01m) of NBA star LaMelo Ball.
• The phrase spread further through Overtime Elite player Taylen “TK” Kinney.
• In March 2025, a teenager filmed yelling “ay, six-seven!” at a game became the “67 Kid” — and reignited a fading trend overnight.
• By October 2025, South Park referenced it repeatedly; the clip drew roughly 1.3 million views in five days.

A throwaway lyric became global culture in about eighteen months. Nobody planned a single step of it.

Anyways, lets continue.

The 1959 study that explains everything

Here’s where most explanations stop — and where the interesting part begins.

In the 1940s, a husband-and-wife team named Iona and Peter Opie began documenting the secret folklore of children: the chants, nonsense words, and inside jokes kids invent and pass to one another with no adult involvement. Their 1959 book, The Lore and Language of Schoolchildren, demolished a popular assumption.

Everyone believed mass media would erase playground folklore. The Opies proved the opposite: it was thriving. Kids used nonsense to cover awkward moments, fill silences, and quietly mock the adult world.

That is exactly what a kid shouting “67” in math class is doing. The behavior isn’t new. We just handed it a phone.

Why your brain falls for it

There’s a psychological mechanism here too: the mere-exposure effect. First studied by Gustav Fechner in 1876 and named by Robert Zajonc in 1968, it’s the finding that we like things more simply from repeated exposure — even total nonsense.

TikTok is a mere-exposure machine. It shows you “six-seven” once, then forty more times. Each repeat makes it feel a little more familiar, a little more yours. You didn’t choose to find “67” funny. It was installed.

The real reason it had to mean nothing

The word “meme” was coined by biologist Richard Dawkins in 1976 — an idea that copies itself from mind to mind, like a gene. And the memes that copy best aren’t the cleverest. They do a social job.

Saying “67” is a test. Laugh, and you’re in. Ask what it means, and you’ve outed yourself as an outsider. The meaninglessness isn’t a flaw — it’s the lock, and being in on it is the key. A phrase with a clear definition can be looked up by anyone. Nonsense can only be understood by being there.

The point of a secret handshake is the people who don’t have one.

It’s the same instinct behind “Kilroy was here,” the meaningless doodle WWII soldiers scrawled everywhere to signal one of us was here. Same behavior. Different century.

The shift

We look at a stadium of teenagers screaming a random number and see decline. The Opies, watching kids chant nonsense in a 1950s playground, saw something else entirely: cooperation, invention, and the simple human joy of a shared secret.

“67” is a generation saying this is ours, and you weren’t supposed to get it. The real Word of the Year was never the number. It was the ancient need to belong to something — to laugh at a thing that isn’t funny, just because your friends are laughing too.

So next time a kid yells “six-seven” and grins at you like you’re hopelessly old, don’t roll your eyes. You’re watching a tradition older than the internet doing exactly what it always has.

You’re just, for once, on the outside of it.
