The chant comes from American rapper Skrilla's 2024 song Doot Doot (6 7), where six seven is repeated as the central hook. It spread through basketball highlight edits on TikTok, then wider after a young fan known online as the 67 Kid was filmed shouting it excitedly at a game. As the phrase became shorthand for the meme, creators made louder remixes like this one, separating the 67 chant from the original track and using it as a standalone reaction for scores, stats and random sightings of the numbers.
