The 67 meme grew out of basketball culture and TikTok in 2025, where the number 6-7 became a running joke linked to tall players and the chant that follows them onto the court. Short clips of children and fans shouting the number spread quickly, turning a simple height reference into a repeatable sound that creators could drop over almost anything. Its appeal lies in repetition rather than meaning, which is why the same chant still appears in sports edits, reaction videos, and classroom humour long after the original clips faded.
