If you’ve scrolled through TikTok recently, you may have heard kids shouting “six-seven!” or noticed the phrase appearing in captions and comments. To many adults, it sounds like it should carry some sort of message—maybe a code, an inside joke, or a new trend with hidden meaning. Surprisingly, it doesn’t have any real meaning at all. That’s exactly why younger users enjoy it. The phrase has become one of those playful internet moments where the humor comes from how random it is, encouraging others to join in simply because it feels fun and energetic.
