1. The “6-7” Meme — A Number That Took Over TikTok

You’ve seen it everywhere: people shouting “6-7!” on TikTok, Instagram, and YouTube without context — and nobody quite knows why. Originating from a clip that used the phrase paired with confusing gestures, it exploded into a global meme that even spilled into real-life interactions, school hallways, and celebrity videos.

What made “6-7” so weird was that it literally means nothing — yet somehow became a universal internet inside joke embraced by Gen Z and Gen Alpha alike.

These absurd creations swept TikTok and Instagram this year, combining surreal visuals, nonsensical audio, and bizarre humor that had no real meaning — yet millions loved it.

The origin traces back to early AI meme creation and quickly spread globally, illustrating how generative AI can create content that is both strangely captivating and utterly meaningless — the heart of “brainrot” internet culture.

It spread rapidly on TikTok, drawing millions of views thanks to its absurd humor and low-effort randomness.

What started as a cultural moment quickly morphed into a worldwide meme, with millions copying the moves — proof that sometimes authenticity becomes its own viral currency.

Though often technically sloppy, the absurdity of “AI slop” made it endlessly shareable and emblematic of how AI influences viral culture.

The craze over Labubu dolls from Pop Mart turned from niche collectible into global obsession.
