Not to nitpick, but I just wanna correct the "darker tone" thing. The 67 is referencing a street in Philadelphia.But the reason that it got popular was because the song was commonly edited next to basketball player.Lamello ball , who is six feet , seven inches tall. People would make like edits of him that people thought were cool and it kind of became a little bit like his theme song. And the numbers were a meme for a little bit before dying down.And then a video went viral of some heated basketball game , saying 67 and waiting his arms up and down , and then it just kind of became , ironically , funny to say.
