8 Teen Slang Terms From The Past That Totally Flopped

Welcome to the wild and ever-evolving world of teen slang—a language where yesterday’s “rad” becomes today’s “slay,” and keeping up can feel like decoding a secret teen diary.

In this post, we’re diving into eight slang terms that have totally fizzled out (sorry, “grody,” you had your moment), and eight that still pack a punch in today’s convos, both online and IRL. From the neon-soaked halls of the ’80s to the scroll-happy feeds of Gen Z, slang has always been a snapshot of what’s cool, weird, or just plain fun to say.

These words reflect the vibes, values, and viral trends of their time—some retired with dignity, others clinging on like a MySpace page.

Whether you’re nostalgic for the days of “gnarly” or trying to figure out if “rizz” is a compliment (spoiler: it is), this journey through teen talk is equal parts flashback and crash course. Let’s decode the lingo!

1. Groovy

Groovy was once the epitome of coolness in the ’60s and ’70s, capturing the essence of the time with its laid-back vibe.

Picture bell-bottoms, tie-dye shirts, and lava lamps, and you’ll understand why this word was on everyone’s lips.

Fast forward to today, and using ‘groovy’ might just earn you a puzzled look or two. It’s like pulling out an old vinyl record at a digital music festival—nostalgic but out of place. While it can still evoke fond memories for some, it’s more likely to be found in retro-themed parties than in casual conversations today.

2. Cowabunga

Thanks to the Teenage Mutant Ninja Turtles, ‘Cowabunga’ became a catchphrase synonymous with extreme excitement and good vibes.

It was the rallying cry of surfers and cartoon fans alike, echoing across beaches and living rooms. However, like a surfboard left in the sun too long, this phrase has faded in popularity.

Today, shouting ‘Cowabunga’ might get you side-eyed unless you’re at a throwback event or surfing nostalgia wave. It’s a word that brings smiles and memories but doesn’t quite fit into the modern slang lexicon.

3. Phat

In the ’90s, calling something ‘Phat’ was the ultimate compliment—it meant cool, stylish, and undeniably awesome.

But try using it now, and you might just confuse people who think you’re mispronouncing ‘fat.’ This slang term was a staple in hip hop culture, where everything from sneakers to beats could be ‘Phat.‘

Despite its once lofty status, ‘Phat’ has largely retired from active duty, much like an old-school track that occasionally gets dusted off for a retro playlist.

4. Radical

A staple of ’80s lingo, ‘Radical’ was used to describe anything extraordinary or cool. From skateboarding tricks to neon fashion, everything could be radical.

Yet, today’s teens might laugh at the thought of using ‘Radical’ in a sentence, unless they’re channeling a nostalgic throwback.

It’s a term that once rolled off tongues like a skateboard down a ramp, but now it’s more like an old VHS tape—memorable, yet outdated. Still, for those who lived through its heyday, ‘Radical’ holds a special place in the heart.

5. The Bomb

In the ’90s, calling something ‘The Bomb’ meant it was the pinnacle of greatness. Whether it was a new pair of shoes or a movie, if it was ‘The Bomb,’ it was top-tier.

However, time and changing news landscapes have not been kind to this phrase. Nowadays, using the term might draw awkward glances or remind people of a different kind of bomb altogether.

It’s a term that thrived in its era but has since retreated to the annals of history, popping up only in nostalgic conversations.

6. Wazzup

The late ’90s saw ‘Wazzup’ rise to fame, thanks to a memorable beer commercial that had everyone mimicking the exaggerated, drawn-out greeting.

For a while, it seemed like every conversation started with this iconic phrase. However, like many fads, it eventually lost its charm.

Today, using ‘Wazzup’ might elicit more eye rolls than laughs, serving as a reminder of how quickly trends can change. Still, it occasionally makes a comeback, usually in a tongue-in-cheek manner.

7. Talk to the Hand

With a flick of the wrist and a sassy attitude, ‘Talk to the Hand’ became the ultimate ’90s shutdown phrase. It was the verbal equivalent of a door slam, perfect for those dramatic teen moments.

Fast forward to today, and using this phrase might just leave people scratching their heads.

While it once delivered maximum sass with minimal effort, it now feels more like a relic of teenage angst past. Nevertheless, it holds a special place in the hearts of those who grew up in its era.

8. Booyah

Once hailed as the ultimate exclamation of triumph, ‘Booyah’ aimed to be the go-to word for celebrating victories.

It echoed through sports arenas and casual conversations alike, offering a punchy way to express excitement.

Yet, despite its initial popularity, it soon became more akin to a flame decal on a minivan—over-the-top and slightly outdated. Today, shouting ‘Booyah’ might bring back fond memories, but it’s more likely to be met with chuckles than cheers.

9. Slay

In today’s slang lexicon, to ‘Slay’ is to excel with style and confidence, whether it’s in fashion, achievements, or just life in general.

Popularized by icons like Beyoncé, this term has transcended its origins to become a universal expression of success and flair.

Unlike some slang, ‘Slay’ hasn’t faded into obscurity; it’s only grown stronger. Whether you’re rocking a killer outfit or acing a presentation, ‘Slay’ is the perfect way to acknowledge someone’s triumphs. It’s a word that’s here to stay, resonating across generations.

10. Bet

‘Bet’ has evolved from a simple agreement into a modern-day affirmation, conveying confidence and certainty. When someone says ‘Bet,’ they’re not just agreeing—they’re committing.

It’s a word that encapsulates trust and understanding, making it a staple in today’s conversations. Whether you’re confirming plans or showing support, ‘Bet’ is versatile enough to fit any occasion.

Its staying power lies in its simplicity and strength, bridging gaps and sealing deals with just one syllable.

In the digital age, ‘Ghosting’ has become an all-too-common phenomenon, referring to the act of disappearing from someone’s life without explanation.

It’s a term that encapsulates the complexities of modern communication, where connections can vanish in an instant. Whether it’s a relationship or a friendship, ‘Ghosting’ leaves a lingering sense of mystery and unanswered questions.

Despite its negative connotations, ‘Ghosting’ remains a relevant part of today’s language, reflecting the changing dynamics of interaction.
