The six seven trend grew on TikTok in 2025 around basketball star LaMelo Ball, whose listed height is six feet seven inches, and the chant is often written as 67. It spread through school hallways, courts and short videos, where children and creators raised and lowered their hands on each number while the beat played. The sound is commonly paired with Skrilla's Doot Doot track, which helped turn a simple height reference into a repeatable joke. Its staying power comes from that simplicity: anyone can join in, and the rhythm fits almost any basketball moment.
