The internet’s new favorite slang term has some users scratching their heads.
While the expression “67” (pronounced “six-seven”) has surged in popularity on social media, the significance of the number remains a mystery to some.
The term’s origins have been traced back to the song “Doot Doot” by Skrilla, in which the rapper frequently recites the lyric, “Six-seven.” The track went viral as a sound on TikTok in late 2024 with thousands of users adding it to their uploads, leading to the song being officially released as a single in February 2025.
Meanwhile, the meaning of “67” has been more debated—and perhaps intentionally so. While some have defined the expression, particularly when paired with a double-handed balancing motion, as meaning “so-so,” content creator Philip Lindsay summed it up as being purposefully puzzling.
“Now it is something that you’re just trying to use to get somebody to reference the number 67,” he said in a TikTok video posted in August. “There is no real meaning to it. It is a number that is fun to say, popularized by a meme with the hand motions, and it just doesn’t mean anything.”
