The slang phrase "six seven" (or "6 7," "67," etc.) originated from a viral rap song called "Doot Doot" by Skrilla, released around December 2024. In the song, "6-7" is used as an adlib or nonsensical line without a specific meaning. However, it became a popular meme and slang phrase primarily on TikTok and among Gen Alpha and Gen Z, often accompanied by hand gestures. "Six seven" essentially means nothing concrete and is used in a variety of contexts with flexible, humorous, or hype connotations. It can be a quirky response to questions like "How tall are you?" or "What time is it?"—where the answer "six seven" is playful rather than literal. The phrase has become a cultural catchphrase, a fun thing to say, and a way for young people to bond and reference the meme. Despite some speculative or humorous theories about origins (like police codes or burial dimensions), it carries no official or fixed meaning and is just a viral trend that spread through social media edits—especially basketball highlight reels using the song's beat and the rapper's cadence.
