Algorithms, Dance Moves, and Catchphrases: The Internet Trends That Actually Stuck Around
For every viral moment that becomes a cultural landmark, there are roughly ten thousand that vanish before you can screenshot them. Remember the cheese-on-baby trend? The pillow challenge? Exactly. But then there are the ones that don't just survive the week — they reroute fashion runways, launch careers, rewrite how music gets made, and permanently add phrases to the American vocabulary.
So what separates a flash-in-the-pan meme from a genuine cultural shift? We dug in. Here are 10 internet trends that crossed the invisible line from "very online" to just... culture.
1. The Renegade — When a Dance Became a Conversation About Credit
The Renegade wasn't just a TikTok dance — it was a cultural flashpoint. Choreographed by Jalaiah Harmon, a 14-year-old Black teenager from Atlanta, the routine went mega-viral in 2019 and 2020, performed by everyone from Charli D'Amelio (who gained millions of followers doing it) to NBA players. But the story that actually had staying power was the credit gap: Harmon wasn't initially recognized for her own creation.
The discourse that followed changed how we talk about appropriation in digital spaces and pushed platforms and creators toward more intentional attribution practices. It also demonstrated that TikTok dances aren't just entertainment — they're intellectual property.
2. "It's Giving" — When AAVE Went Everywhere
African American Vernacular English has always been the engine of American slang, but TikTok turbocharged the pipeline. "It's giving," "no cap," "understood the assignment," "slay" — these phrases moved from Black digital creators into mainstream usage at a speed that was genuinely unprecedented.
Love it or critique it (and the conversation about linguistic appropriation is very real), the linguistic influence of Black TikTok creators on everyday American speech is undeniable. Ad agencies, morning news anchors, and your mom's book club have all made contact.
3. Cottagecore — Aesthetic Movements as Mainstream Fashion
Before TikTok, aesthetic subcultures mostly lived on Tumblr and stayed there. Cottagecore — think prairie dresses, mushroom imagery, baking bread, romanticizing rural simplicity — made the leap. By 2020, it had landed on the runways of Rodarte and Batsheva, influenced Gucci campaigns, and driven sales of flowy linen dresses through the roof on every major retail platform.
It proved that when an aesthetic gains enough traction on short-form video, fashion houses are watching — and reacting fast.
4. Lil Nas X's "Old Town Road" — How Viral Becomes Grammy-Winning
This one's a landmark. "Old Town Road" started as a meme — specifically a yeehaw meme — on TikTok in early 2019. Within months it became the longest-running number-one single in Billboard Hot 100 history. The song's journey from ironic internet joke to mainstream juggernaut rewrote industry assumptions about TikTok as a music discovery platform and opened doors for artists who understood how to work the algorithm.
Record labels noticed. Their entire A&R strategy has never been the same.
5. The "Devious Lick" and the Power (and Limits) of Challenge Culture
Not all cultural crossover is positive. The Devious Lick challenge — in which students filmed themselves stealing increasingly absurd items from school bathrooms — caused actual property damage across the country in fall 2021 and prompted school districts and local governments to respond publicly.
It's a case study in how viral challenges can generate real-world consequences, and it forced a more serious conversation about TikTok's responsibility in moderating harmful trends. The challenge culture it represented — good, bad, and chaotic — has become a permanent feature of how brands, schools, and even politicians now have to think about social media.
6. Feta Pasta — When TikTok Rewrote the Grocery List
Baked feta pasta. If you were on TikTok in early 2021, you know. The recipe went so viral that feta cheese sold out at grocery stores across the United States. That's not a metaphor — actual supply chain disruption caused by a pasta video.
It signaled the arrival of "food TikTok" as a legitimate force in American food culture and eating habits, and it proved that the platform's influence extended well beyond entertainment into consumer behavior in the most tangible possible way.
7. Beige Flags and Relationship Taxonomy
TikTok has become the unofficial glossary of modern relationships. "Beige flags" (quirks that aren't red flags, just... odd), "situationship," "breadcrumbing," "love bombing" — these terms have migrated from niche psychology circles and dating app discourse into mainstream relationship conversations. Therapists use them in sessions. They appear in New York Times relationship columns. They're how a lot of Americans now describe what's happening in their dating lives.
Language is culture, and TikTok has become one of the most active sites of American emotional vocabulary-building.
8. "Main Character" Energy — Narrative Identity in the Feed
The "main character" trend — filming yourself as the protagonist of your own cinematic life moment, often set to dramatic music — became shorthand for a whole philosophy of self-presentation. But more than that, it seeped into marketing, into self-help language, into how brands talk to consumers. "You're the main character" became a genuine advertising hook.
It also sparked meaningful pushback about individualism and social media narcissism — which itself became content. The meta-loop was complete.
9. Hyperpop and the Algorithmic Music Genre
Hyperpop — the glitchy, maximalist, deliberately abrasive microgenre — found its widest audience through TikTok. Artists like 100 gecs, Charli XCX, and later a wave of bedroom producers built audiences through short-form video that traditional radio would never have touched. The genre influenced mainstream pop production in ways you can hear on the charts right now — that processed, pitched-up vocal sound isn't going anywhere.
TikTok didn't create hyperpop, but it gave it oxygen and proved that algorithmic discovery could incubate entire genre movements.
10. The Stanley Cup Craze — When Utility Becomes Identity
A water bottle. A water bottle became one of the defining consumer obsessions of 2023-2024, driven almost entirely by TikTok. Stanley's Quencher tumbler went from a camping supply staple to a status symbol, with limited-edition colorways selling out in minutes and reselling for multiples of retail.
It's a perfect encapsulation of how internet culture now operates: TikTok identified a functional product, aestheticized it, attached identity and community to it, and turned it into a phenomenon that landed on the front page of actual newspapers. The brand responded in real time, collaborating with influencers and dropping limited colors. The loop between online culture and consumer capitalism has never been tighter.
The common thread across all of these? They didn't just go viral — they meant something to the people who engaged with them. Whether it was identity, community, language, or aesthetics, each one tapped into something people actually wanted to express or explore. That's the difference between a trend and a moment that moves culture. And in the feed economy, that distinction is everything.
