The Six Seven 67 chant grew out of TikTok in 2025, where creators turned the basketball star LaMelo Ball's listed height of six feet seven into a sing-song catchphrase, often set to Skrilla's track Doot Doot (6-7). School hallways, sports edits and reaction videos quickly adopted the call-and-response, with users moving their hands up and down as they chanted the numbers. Its appeal lies in how easy it is to copy, recognise and drop into almost any clip, which kept it circulating long after the original trend peaked.
