If you’ve heard your child suddenly shout “six seven!” in the car, at dinner or even in the middle of class, you’re not alone.
The phrase has become one of the biggest kid trends of 2025. But where did it come from, what does it mean and should parents be worried?
What exactly is “6-7”?
“6-7” doesn’t mean much at all. Kids repeat it because it’s fun. The phrase is often used as a punchline, as a response when someone says the numbers “six” and “seven” or dropped into conversations just to get a laugh.
The phrase traces back to a 2024 rap song called “Doot Doot (6 7)” by Skrilla that went viral on TikTok, where users paired it with videos of athletes and celebrities.
There were lots of videos created of NBA star LaMelo Ball, who happens to be 6-foot-7. Soon, memes and edits were everywhere.
Why do kids keep saying it?
Psychologists note that kids often latch on to silly, rhythmic words because they’re easy to say and connect bonds.
Repeating “six seven” also creates an inside joke among kids, something they understand and adults often don’t.
How are kids using it?
- As a random shout: blurting it out at unexpected moments.
- As an inside joke: saying it in groups, sometimes in unison, just to make each other laugh.
- In digital content: TikTok edits, Instagram Reels and memes.
- At school: some teachers even report having to ask students to stop shouting “six seven” in class.
Is it harmless?
For most kids, yes. “Six seven” is a phase and will likely fade as the next big meme takes its place. Still, there are a few things to know:
- The original song that sparked the trend contains explicit lyrics. Kids often only repeat the numbers, but it’s good to be aware.
- If the phrase becomes disruptive at school or obsessive at home, it’s worth reminding kids about when and where it’s appropriate.
