There’s a particular moment that many parents and teachers recognize: a child says something with complete confidence, and the adult in the room has absolutely no idea what just happened. Generation Alpha, the cohort born between 2010 and 2024, has grown up amid a digital revolution that has shaped not just how they communicate, but the very vocabulary they use to do it. By 2026, their slang has become its own dialect, and it’s evolving faster than most adults can track.
Since this group grew up in a digital age, most of their slang comes from their many forms of communication, like YouTube, TikTok, Instagram, Roblox, school, and friends. What makes Gen Alpha’s language especially hard to crack is that many of these words aren’t in any dictionary. They emerge from streaming clips, viral memes, and gaming culture, then spread at a speed that makes traditional language change look glacial. Here are four terms that regularly leave adults staring blankly.
1. "Fanum Tax" – The Official Excuse for Stealing Your Food

Fanum Tax refers to a running gag from Twitch streamer Fanum’s streams, in which he “taxes” other members of the AMP creator group, like Kai Cenat, when they’re eating food, taking a small part of their meal. The phenomenon started on AMP streams in late 2022, spreading via clips on YouTube and TikTok. The concept is straightforward in its absurdity: when a friend is eating, you’re entitled to a small cut. Think of it as an unofficial toll on shared meals.
The American streamer Fanum, known in real life as Robert Gonzalez, created the idea of “taxing” his fellow streamers and content creators by taking bits of their food when streaming alongside them. He famously burst into a stream hosted by Kai Cenat and snatched a plate of cookies, which became a recurring joke between the pair, before spreading among other Twitch streamers and creators on TikTok videos and YouTube. By late 2023, the phrase had jumped from niche streaming humor into actual school cafeterias across the country. In late 2023, the phrase “Fanum tax” became a widely used slang term among Gen Z and Gen Alpha members, resulting in satirical usage that parodied the phrase’s over-usage.
2. "Ohio" – A State That Became a Synonym for Weird

The Gen Alpha slang use of Ohio as an insult originated on the internet shortly after a series of memes about the US state of Ohio began circulating in the late twenty-teens. The state itself never did anything to deserve this fate, but the internet rarely operates on fairness. The term’s origins are derived from an older meme known as “Only in Ohio,” which would list strange situations or images captioned by some variation of the phrase. That meme was created following a viral Tumblr post in 2016 of a broken bus stop sign that said “Ohio will be eliminated,” which kicked off the Ohio trend.
Ohio functions like an insult in Gen Alpha slang. If someone calls you an Ohio, or says something is “Ohio,” it means you’re cringe, weird, or embarrassing – basically the opposite of having rizz. The term stems from memes about Ohio being a strange or cursed place, though it has nothing to do with the actual state. It’s used to describe awkward, uncomfortable, or deeply uncool situations and people. Telling a kid their outfit is “so Ohio” carries real social weight in their world, even if the adults nearby have no idea what was just said.
3. "Sigma" – A Greek Letter That Now Means Everything and Nothing

Sigma means “good” and can be used much like the word good itself – it works in almost any situation. A sigma can also refer to someone who’s cool, confident, and stands out from the crowd. The term originally circulated in certain internet subcultures to describe a lone wolf type, someone who operates on their own terms rather than following social hierarchies. Sigma was originally used for those who go their own way, focusing on self-improvement and independence rather than following the crowd. If you’re giving off “sigma vibes,” you’re the strong, silent type.
This word has since taken on a broader meaning, which is entirely interchangeable, and can be a substitute for most words. That’s what makes it particularly baffling for adults: it can be a compliment, a descriptor, an exclamation, or even a comedic substitute for almost any noun or adjective. You might hear someone say “that’s so sigma” to describe anything positive or impressive, and it’s even a term that can come up during fun conversations when kids are trying to show off what they think is cool. The phrase “What the sigma?” – popularized through a SpongeBob meme – became a kind of all-purpose reaction that means almost nothing specific, yet kids use it constantly.
4. "Brainrot" – When the Internet Consumes You Completely

Gen Alpha’s hyper-online manner of speaking has been dubbed “brainrot,” mostly by older Gen Z’ers who share spaces like TikTok with them. It describes the phenomenon of consuming so much nonsensical internet content that you start randomly referencing memes. Unlike most slang terms, this one is somewhat self-aware – kids use it to describe their own internet habits with a mixture of pride and irony. It’s a self-deprecating term the kids use themselves to describe content that is nonsensical, fast-paced, and seemingly meaningless to anyone over the age of 20.
The slang can be quite tricky to learn, largely due to its ever-changing nature. Brainrot sits at the center of this problem for adults, because it doesn’t just describe a single word or behavior. It refers to an entire mode of communication, one built from layered internet references that only make sense if you’ve spent serious time on TikTok or in gaming communities. Gen Alpha kids are online pretty much all the time. They live and breathe TikTok trends, Twitch catchphrases, and Reddit memes. Once a new slang phrase is born, it tends to spread like wildfire. Calling someone’s humor “brainrot” is actually, in their world, a form of recognition rather than an insult.
What’s striking about all four of these terms is that none of them follow the usual logic of how slang gets made. They come from memes, streamers, viral clips, and internet rabbit holes that most adults simply aren’t inside of. Gen Alpha has grown up in a fully digital world, which has had an impact on the words they use. Most of their slang is closely related to internet slang and culture. In that sense, decoding their language isn’t really a vocabulary problem. It’s a window into where they spend their attention and who they trust enough to imitate.
