“What Is 6 7?” The Viral Math Mystery Everyone’s Googling—Solved in Under a Minute

Anyone with tweens or teens has likely heard the sudden shout of “six-seven!”—and parents are racing online to ask “what is 6 7?” Here is the quick answer and why the mysterious number is everywhere. What Is 6 7? “6-7” (also written 67, 6 7 or six seven) is a viral, meaning-free catchphrase that exploded on TikTok in early-2025. The snippet comes from rapper Skrilla’s drill track “Doot Doot (6 7),” but users quickly detached the digits from the song and turned them into a stand-alone exclamation with matching up-down hand motions. The meme snowballed after high-school basketball star Taylen “TK” Kinney—listed at 6 ft 7 in—kept chanting it in Overtime Elite videos, and a clip of the now-famous “67 Kid” screaming the phrase at a game sealed its mainstream takeover. Why Does It Have No Meaning? Part of the appeal is precisely that it doesn’t mean anything. Gen Alpha creators say the randomness makes classmates laugh, confuses adults and sidesteps moderation filters that flag real profanity. Linguists compare it to earlier nonsense memes like “Skibidi” or “Ohio,” labeling it “brain-rot content” designed for quick dopamine hits. How the Trend Spread Beyond TikTok 1. Sports arenas: NBA, WNBA and college crowds chant “6-7” during timeouts. 2. Classrooms: Teachers report lessons derailed when a slide shows the numbers six or seven. 3. Marketing stunts: Pizza Hut sold 67-cent wings, McDonald’s UAE packed seven nuggets in a six-piece box, and Clash Royale dropped a 67 wizard emote. 4. Politics: U.S. Vice-President JD Vance joked about banning the number, while Britain’s Prime Minister apologized for joining a banned “6-7” gesture during a school visit.
