Label Value
First notable appearance 2025 on TikTok and Instagram Reels
Dictionary inclusion Merriam-Webster slang dictionary (2025)
Primary form Spoken phrase, written as 6‑7 or 67

What does 67 mean in slang?

Where did “6-7” originate?

  • Most accounts trace the viral phrase to the drill rap song “Doot Doot (6 7)” by Philadelphia rapper Skrilla (Wikipedia).
  • Merriam-Webster also confirms the song as the source sound behind the slang.
  • The meme was amplified by edits featuring NBA player LaMelo Ball, who is 6′7″ tall (Wikipedia).

What does Merriam-Webster say?

  • Merriam-Webster defines “six seven” as “a nonsensical expression used especially by teens and tweens” (Merriam-Webster).
  • The dictionary notes the phrase is connected to a rap song and to a basketball player who is 6′7″ tall (Merriam-Webster).
  • It is commonly written as “6-7,” “67,” or “6 7” (Wikipedia).
The paradox

Teens adopted “6-7” precisely because it has no fixed meaning. For a generation that constantly negotiates identity online, a blank-slate phrase can signal group membership without saying anything concrete.

Why this matters: the very ambiguity that frustrates adults is what fuels the meme’s viral spread.

Why are kids chanting 6-7?

Is the chant harmful?

  • Teachers on Reddit report students standing up and chanting “6-7” in classrooms, often to get a reaction (cited in Merriam-Webster).
  • Psychologists quoted in FOX 5 New York say these trends are “not harmful” and actually a way for kids to bond and connect.

What do psychologists say?

“These trends are not harmful – they’re actually a way for kids to bond, feel included, and connect with their friends.”

— Psychologists (via FOX 5 New York)

  • The chant is part of a broader pattern of nonsensical teen slang that cycles every few months.
  • Reddit teachers note the behavior is disruptive but not malicious.

The pattern: the louder the chant, the more it reinforces the in-group. For parents and educators, ignoring the phrase often defuses it faster than reprimanding.

What to watch

If the chant becomes a classroom distraction, the best response is a calm acknowledgment followed by redirection. Punishing the phrase only gives it more power.

The implication: the chant’s power comes from its opacity, not its content. Adults who react strongly only reinforce its appeal.

What is TikTok 67?

What is the “Merry Rizzmas” connection?

  • A viral variation pairs “6-7” with “Merry Rizzmas,” creating the phrase “6-7 on a Merry Rizzmas” (Wikipedia).
  • This mashup of holiday greeting and slang became a separate TikTok trend in late 2025.

How is the hand gesture performed?

  • The gesture typically involves holding up fingers to represent the numbers six and seven, often with an up-and-down motion (Merriam-Webster).
  • On Instagram Reels, users flash the gesture while mouthing “6-7” as a nonverbal punchline.

The catch: the hand gesture exists mainly as a visual hook for short-form video. Without the audio, it looks like a random finger count — which is part of the joke.

What does it mean to be 6-7?

Is it used as an exclamation?

  • Yes – most often as an interjection when someone encounters or hears the numbers 6 and 7 (Merriam-Webster).
  • Teens described it to FOX 5 New York as a “filler word that doesn’t really mean anything.”

Can it mean “so-so”?

  • Merriam-Webster reports that some people interpret “six seven” to mean “so-so” or “maybe this, maybe that” (Merriam-Webster).
  • FOX 5 New York also notes the term can be used as shorthand for “something that’s okay – kind of six seven.”

The trade-off: the phrase can mean almost anything, which makes it useful as a conversation filler but also leaves adults guessing.

Why is saying 6-7 rude?

Is there an inappropriate meaning?

  • No verified inappropriate definition exists in any authoritative source (Merriam-Webster; Wikipedia).
  • Some adults perceive the term as rude because its mystery can feel like a secret code designed to exclude them.

What do teachers report?

  • Teachers report students using “6-7” specifically to get a reaction from authority figures (cited in Merriam-Webster).
  • The behavior is not malicious but fits into a long history of “anti-language” used by youth to create boundaries.
The catch

Calling the phrase “rude” without evidence risks alienating teens. The word itself is neutral; the intent behind its use determines whether it’s disrespectful.

What this means: the offensiveness, if any, lies in the delivery and context, not the dictionary definition.

What do 6 and 7s mean?

What is the idiom “at sixes and sevens”?

  • The idiom “at sixes and sevens” means in a state of confusion or disorder – dating back to the 16th century (Onestopenglish).
  • It has no direct connection to the 2025 TikTok meme.

How does it differ from the modern slang?

  • The modern “6-7” is a blank meme; the idiom has a specific meaning related to chaos or disagreement.
  • Despite the numerical overlap, the two phrases share no origin or cultural lineage.

The implication: parents or educators who confuse the two may underestimate the novelty of the teen slang. It’s a fresh creation, not a mutation of an old idiom.

Timeline: How 6-7 Spread

Three phases, one pattern: the meme moved from a niche rap track to dictionary inclusion in under a year.

  • Early 2025: First viral videos on TikTok using “6-7” as a nonsensical chant and hand gesture (Wikipedia).
  • Mid 2025: Merriam-Webster adds “six seven” to its slang dictionary; Reddit teachers report classroom chants (Merriam-Webster).
  • Late 2025: Wikipedia creates an article for “6-7”; the phrase spreads to Instagram Reels and other platforms (Wikipedia).

The pattern: what began as a line in a drill rap became a gestural meme, then a dictionary entry, reflecting how fast internet culture can institutionalize nonsense.

Expert Perspectives

“These trends are not harmful – they’re actually a way for kids to bond, feel included, and connect with their friends.”

— Psychologists (via FOX 5 New York)

“Six seven (or 67 or 6 7, etc.) is a nonsensical expression used especially by teens and tweens.”

— Merriam-Webster

“While some interpret the phrase to mean ‘so-so’ or ‘maybe this, maybe that,’ it is also used as an exclamation.”

— Arianna Huffington (via Facebook)

The consensus across sources: the term lacks a single meaning, and its power lies in that emptiness.

Bottom line: “6-7” is not a coded message or a secret signal. It is a blank canvas that teens use to mark belonging. For parents: don’t overreact, and don’t try to decode it – there’s nothing to decode. For educators: a calm redirect works better than a reprimand. For other adults: if a teen says it to you, the only correct response is a shrug and a smile.
