The six seven chant grew out of the viral 6-7 meme that spread across TikTok in 2025, where creators shouted the numbers as a random hype call in sports clips, gaming videos and everyday moments. It is linked to basketball star LaMelo Ball, who stands six feet seven inches tall, and was amplified by the song Doot Doot (6 7) by Skrilla. Children picked it up in classrooms and playgrounds, turning it into a shared joke, and creators still use the short sound because it is instantly recognisable, easy to repeat, and funny precisely because it means almost nothing.
