The phrase comes from Skrilla's 2024 track Doot Doot (6 7), where the numbers are chanted as a hook. It spread on TikTok in early 2025 through basketball edits, especially clips linked to LaMelo Ball, who is listed at six feet seven inches tall. From there the chant escaped the song and became standalone slang, repeated in classrooms, comments and short videos with little context. Its popularity comes from that randomness, as fans use the sound to signal they are in on the trend.
