The 6-7 joke spread on TikTok and short video platforms in 2025, growing out of the song Doot Doot by Skrilla and its repeated height reference, then linking in edits to basketball player LaMelo Ball, who is listed at 6 feet 7 inches. From there 67 became a standalone chant that fans shouted, commented and remixed far beyond its original context. It stays popular because it needs no explanation, works as an inside joke, and can be dropped into almost any clip for instant recognition.
