6-7 (pronounced "six seven"; also written as 67 or 6 7) is an Internet meme and slang term that emerged in 2025 on TikTok and Instagram Reels] and then later spread to YouTube Shorts. It has no fixed meaning.

The phrase originated from the song "Doot Doot (6 7)" by Skrilla, which became popular in video edits featuring professional basketball players, especially LaMelo Ball, who is listed at 6 ft 7 in (2.01 meters) tall. The meme was further popularized through Overtime Elite player Taylen "TK" Kinney's repeated use of the phrase.

The meme, described as "annoying" and "like a plague",[7] has been linked by multiple news outlets to the wider "brain rot" phenomenon.
