The chant comes from the viral 6-7 trend that spread on TikTok in 2025, linked to basketball culture and the repeated lyric in the song Doot Doot. Players, fans and creators turned a simple height reference into a call and response joke, and the looped version became known as a standalone 67 meme sound. Its popularity is less about the numbers themselves and more about how easily the rhythm fits edits, comments and remixes, which is why it keeps resurfacing whenever a post mentions six, seven or tall players.
