Language is a fascinating reflection of the times we live in. Just as fashion and technology evolve, so does the slang we use. Baby boomers, who grew up in a world with rotary phones, vinyl records, and a different media landscape, have a distinctive way of speaking that is often foreign to today’s generation. Gen Z is immersed in a universe of TikTok trends, internet slang, and memes, but many boomer expressions sound like artifacts from another era.
Here’s a look at words and phrases that are still part of the boomer lexicon but have been largely left behind by Gen Z.
Moo Juice – A Playful Term for Milk

“Moo juice” was once a playful, affectionate way to refer to milk, especially when talking to children. It’s a piece of boomer slang rooted in a simple, almost childlike sense of wordplay: cows moo, cows make milk.
Today, Gen Z is more likely to simply call it “milk,” with little room for cutesy terminology. “Moo juice” has become a quaint, retro term that’s used mostly for nostalgia, but it’s not part of the modern lexicon.
Boob Tube – The Old School TV
The “boob tube” was once a snarky term for the television, mocking its cathode-ray tubes and, more broadly, the perceived mind-numbing effect of too much TV. Boomers grew up hearing warnings about the dangers of staring at the screen for too long, often from parents concerned about their children’s “brain rot.”
In today’s world of flat-screen TVs, streaming services, and smart devices, “boob tube” feels hopelessly dated. Gen Zers, who have never known a world without high-definition televisions and personalized content, have no use for the term. For them, the term is mostly a humorous reference to a bygone era.
Fink – The Tattletale
In boomer-era slang, to “fink” on someone meant to snitch, betray, or rat someone out. The word originated in labor disputes and criminal circles, but it found its way into schoolyards and teen dramas of the ’60s and ’70s.
For Gen Z, the term is laughably old-fashioned, and they are more likely to say “snitch,” “rat,” or “op.” If a boomer calls someone a “fink,” it might sound like they’re quoting a character from an old cartoon, instantly revealing their generational gap.
Threads – The Stylish Wardrobe

In the boomer era, “threads” was a term for someone’s clothing, often used in a complimentary sense. “Check out his threads!” would be the equivalent of today’s “fit” or “outfit,” and it carried a cool, vintage vibe.
But with the rise of social media and ever-changing fashion trends, the word “threads” has mostly fallen out of use. Gen Z, who are constantly updating their fashion terminology, is more likely to use terms like “drip” or “fit.” Interestingly, “threads” has recently become associated with a social media platform, muddying its original meaning even further.
Bummer – A Mild Disappointment
Boomers are still fond of the word “bummer,” a lighthearted way to express mild disappointment or sympathy. “That’s a bummer” could refer to anything from a canceled concert to a minor setback. It was ubiquitous in the ’60s and ’70s.
While some Gen Zers might still understand the term, they are more likely to use phrases like “L,” “rip,” or “that’s rough” to convey similar sentiments. “Bummer” just doesn’t hold the same weight in their vocabulary, making it one of the few boomer words that has retained some popularity across generations, though it’s rapidly fading.
Zonked (or Zonked Out) – Totally Exhausted
When boomers talk about being “zonked” or “zonked out,” they’re referring to being completely exhausted, often after a long day or intense physical activity. It’s a term that conjures images of worn-out parents crashing on the couch after a busy day.
Gen Z, who are accustomed to a fast-paced lifestyle fueled by energy drinks and constant social media updates, rarely uses the word. Instead, they prefer saying “I’m dead,” “I’m wiped,” or “I’m cooked.” These phrases reflect the high-energy nature of the modern world, where exhaustion is often linked to overstimulation rather than simple fatigue.
The Fuzz – The Police

The term “the fuzz” was once a casual way to refer to the police. It emerged from the counterculture of the ’60s and ’70s, when law enforcement was seen as the enemy or as part of the establishment to oppose. Its use was widespread in crime films and popular culture during that time.
In contrast, Gen Z has its own terms for law enforcement, such as “the cops” or “12.” For most younger people, “the fuzz” feels like something out of an old black-and-white movie or a dated meme.
