The clip comes from a Nexo_edits short titled as an SCP-67 kid edit, pairing the 67 meme with the track Eclética Nanolícita 2. That format spread through YouTube Shorts and TikTok, where editors remixed the same chant and beat into quick, looping jokes. The numbers six and seven became a shorthand fans recognised instantly, even without the original video. It remains popular because the edit is short, loud and easy to drop into other brainrot compilations, gaming clips and reaction edits without needing any setup or explanation at all.
