From a playful social media joke to a full-blown catchphrase, the 6-7 craze has undoubtedly become the meme trend most remembered in 2025. Reproduced by millions, including celebrities like Shaquille O’Neal, the viral chant reached its peak in one of the most-viewed videos of the year, filmed just a few weeks ago at an In-N-Out location in L.A.
Today, fans of this numerical trend woke up to the news that the beloved burger chain has made the drastic decision to remove that number from its order tickets, a move similar to what they did decades ago with another controversial number, 69.
According to People, the measure has not been officially announced by the chain’s executives. However, it has surfaced that orders numbered 67 are no longer available, based on reports from users on social platforms like X and Reddit. It’s also unclear whether the decision applies to all locations or only to the ones reported on social media.
What’s the 6-7 meme all about?
It all started with the song Doot Doot (6 7) by Skrilla, and the lyrics that repeatedly shout “6‑7.” That track got remixed into TikToks and Shorts, often paired with clips of tall‑ish basketball players (especially those who stand 6’7”), giving the phrase some random association with height and hype.
From there, “6‑7” evolved into a kind of digital and absurd inside joke, but delivered with dramatic flair: people screaming it, making hand gestures, chanting “six‑seven” for no reason other than that it’s trending.
