The answer is surprisingly complex, rooted in child psychology, peer influence, and the innate need for belonging.

What Is the ‘Six Seven’ Trend?

Recently, a new trend has swept through elementary schools and playgrounds: kids incessantly repeating the phrase “six seven”. There’s nothing particularly funny about these numbers, nor do they signal a hidden code adults are missing. Yet, this nonsense phrase has caught on. Videos, social media posts, and parent forums all point to this identical behavior popping up across the country — and even the globe.

The real question is not why ‘six seven’ specifically, but why do kids globally lock on to such strange, seemingly meaningless phrases?

Why Do Kids Repeat Weird Phrases?

Kids have always picked up and run with quirky language trends, whether it was “yada yada yada,” “Bazinga!” or now, “six seven.” According to developmental psychologists and parenting experts, there are several overlapping reasons this happens:

  • Cognitive Development: Children between the ages of 5 and 10 are actively experimenting with words and sounds as a way to explore language. Repetition helps them master linguistic patterns and test boundaries.
  • Finding Humor: Kids crave laughter and delight in the silly or absurd. Random phrases that sound strange or out of place invoke giggles and create inside jokes within peer groups.
  • Social Bonding: Sharing a catchphrase fosters a sense of group identity. Kids who repeat the same phrase are more easily welcomed into social circles—they’re “in” on the joke.
  • Seeking Attention: Sometimes, kids realize that saying “six seven” gets a big reaction from adults — be it laughter, confusion, or playful annoyance.

Repeating phrases, even nonsensical ones, is not only normal but expected for growing brains. It’s also harmless in most cases and reveals key aspects of childhood culture.

The Role of Belonging and Peer Influence

According to parenting experts, including Dr. Becky Kennedy, a clinical psychologist known for her modern, compassionate parenting advice, the “6 7” trend is less about the numbers and more about a child’s natural drive to feel connected and included.

  • Belonging Is Core: Children gravitate toward whatever makes them feel like part of a group, which can be something as simple as a code word or repeated phrase.
  • Peer Power: If a classmate or influencer latches onto a phrase, it quickly spreads among the peer group. It’s viral, not because of social media, but because of how kids build relationships.
  • The ‘Secret Club’ Effect: Being ‘in the know’ gives kids a sense of exclusivity and importance, boosting confidence and social status.

Language, Play, and Building Identity

While it might feel random to adults, repeating unique phrases is actually a vital part of how kids test the boundaries of communication:

  • Practice: Playing with sounds allows children to experiment with word construction, rhythm, and how language evokes emotion.
  • Autonomy: Coming home repeating a phrase is often a child’s way of expressing independence — proof of experiences and friendships outside the family.
  • Humor and Inside Jokes: Shared language reinforces friendship bonds, making kids feel as if they share a special understanding unavailable to outsiders.

In short, these trends are far from meaningless: they are a language of connection, comfort, and play.

How Should Parents Respond?

Hearing your child mindlessly repeat a nonsense phrase can be exasperating, especially when it happens for days on end. However, how you react can make a big difference. Here are evidence-based responses for parents:

  • Stay Curious, Not Critical: Instead of dismissing or rolling your eyes, try to ask your child where the phrase started or what they like about it. This opens up dialogue instead of shutting down a piece of their world.
  • Join the Play: Jump in and say the phrase along with them — it sends the message that you’re interested in their world and builds trust.
  • Set Boundaries (When Needed): If the repetition turns disruptive (like shouting it in public), calmly explain why certain times or places aren’t appropriate for loud play.
  • Avoid Shaming or Punishing: Remember, this behavior is a sign of development, not defiance. Negative reactions may make the phrase feel taboo, increasing its allure.
  • Encourage Broader Conversation: If the phrase becomes a default answer (to every question!), gently redirect the conversation without scolding. For example, “I hear ‘six seven’ — I’m also interested in what you did in art today!”

What If It Goes Too Far?

While most kids will eventually grow bored with a phrase and move on, sometimes it can cross the line into disruptive or obsessive territory. Here’s when to take note:

  • The phrase is said in inappropriate settings for extended periods, affecting school or home routines.
  • Your child gets stuck and has difficulty stopping the repetition, even when requested.
  • The repetition seems to intrude on friendships or lead to social isolation.

If any of these occur, it’s a good idea to discreetly check in with teachers, observe for other behavioral signals, and, if concerned, consult with a child behavior professional. Otherwise, rest assured that this is a fleeting stage.

Is This Normal for Their Age?

Absolutely. Language-based trends and memes are developmentally typical from preschool through the pre-teen years. As children’s brains mature, the appeal of repetitive nonsense wanes, replaced by more sophisticated forms of humor and in-group language. In adolescence, verbal quirks might become slang or pop culture references instead of pure nonsense.

The Real Takeaway

Whether they chant “six seven,” “banana phone,” or another oddball phrase, kids aren’t just being weird — they’re growing. This kind of repetition is a healthy, albeit sometimes annoying, sign of:

  • Social learning and connection
  • Linguistic exploration
  • Confidence in individuality
  • Emotional comfort through shared humor

Instead of trying to stomp out the trend, see it as an invitation into your child’s world — one that will evolve as they do. So next time you hear “six seven” for the hundredth time, remember: it’s just childhood at work.
