Breaking across global social feeds this week: the phrase “6-7” (pronounced “six-seven”) has been crowned the word of the year by Dictionary.com after erupting into viral youth culture. At first glance it means nothing—just a number—but teens and tweens worldwide have adopted it as a badge of curiosity and confusion. What started as a viral clip set to Doot Doot (6 7) by Skrilla, then ballooned into a meme-tag used in classrooms, chat groups and trending videos. > “Used especially by teens and tweens,” says the site of the year-making term.
Online analysts say the fascination lies in the phrase’s emptiness—no clear definition, no fixed meaning, just a collective “inside joke” that cuts across borders. It’s being wielded as both a nonsensical chant and a clever signifier: if you get “6-7”, you’re in the club. The trend even echoes the broader “brain-rot meme” culture where absurdity becomes culture.
