The term "67" (pronounced "six-seven") is a viral internet meme and slang term that largely has no fixed meaning. Popularized by Generation Alpha on social media platforms like TikTok, it is often used as a nonsensical response or to describe something as "so-so" or "mid".
Origin of the "67" meme
Viral song and basketball player: The phrase originated from the song "Doot Doot (6 7)" by the rapper Skrilla. It became widely popular in basketball-related video edits on TikTok featuring players, especially LaMelo Ball, who is 6 feet, 7 inches tall.
"67 Kid": In March 2025, a boy at a basketball game was captured on video enthusiastically shouting "67!" with a hand gesture. The video went viral and further propelled the meme into the mainstream.
Intentional ambiguity: Many people, including the rapper who created the song, believe the meme's popularity is rooted in its very lack of meaning. Its confusing and absurd nature is part of the appeal for its Gen Alpha audience.
Spread to schools: The phrase spread offline, with teachers reporting students shouting "67" in classrooms. It has become an inside joke for those in on the trend.
Common uses of the term
The meaning of "67" depends heavily on context, tone, and accompanying gestures. It can be used:
As a nonsensical response: When used randomly, it acts as a shibboleth, or inside joke, for those familiar with the meme.
To mean "so-so" or "mid": When accompanied by a balancing hand gesture, it can mean "undecided" or indicate that something is mediocre.
For dismissal: In some contexts, it can be a quick way of telling someone to "go away" or "get lost".
