The phrase comes from the 2024 song Doot Doot (6 7) by rapper Skrilla, where the hook repeats the numbers over the beat. TikTok edits in early 2025 linked it to basketball player LaMelo Ball, who is listed at 6 feet 7 inches, and the chant spread through sports highlights, school videos and comment sections as simple 67 spam. It soon lost any single meaning and became generational slang, repeated for the reaction it gets, which kept the sound in constant use across meme pages.
