A nine‑year‑old’s bafflement over the viral phrase “6‑7” sparked a wider look at how meaningless memes now flood everyday conversation. The catchphrase, lifted from a rapper’s track and amplified on TikTok, spread to schoolyards and even political speeches without any substantive meaning, exposing the platform’s power to shape language overnight.

Research from Pew Research shows a tiny elite drives most online output: on Twitter, 25 % of accounts generate the bulk of posts, while on TikTok the top 25 % of users produced 98 % of publicly visible videos. This concentration forces the majority to echo popular memes to stay visible, turning slang into a commodity rather than organic culture.

For advertisers and brand strategists, the takeaway is clear: cultural relevance now hinges on mastering algorithmic echo chambers. Companies that can insert their messaging into the meme loop gain instant traction, while those that ignore it risk obsolescence. The meme economy has become a decisive factor in digital marketing spend.
