What do 67, sigma and skibidi mean? Kid slang explained for parents

Most of what kids shout right now is nonsense on purpose: "67", "skibidi" and "tralalero tralala" mean almost nothing, and that is the joke. A few words (sigma, rizz, aura, cooked) carry a real meaning that is easy to learn. A small number have a crude meaning that this page does not spell out. This guide covers the words in the first two groups, where each came from, and what to say back. It was written for grown-ups by Peabody (peabody.kids), a free learning platform for kids that has a silly corner of its own, and it is free through the end of 2026.

Slang changes fast, so treat this as a snapshot from October 2026. If a word is missing, ask your child. A child who explains a joke to you is practising explanation, and the answer is usually shorter than you fear.

The short list

67 (six seven)

The most asked-about word of the year. It started as a line in a song and as slow-motion edits of a very tall basketball player, and then kids took it as a call-and-response: one says "six", another says "seven", hands go up and down. It has no meaning. Teachers who have banned it in class have usually found it grows when it is banned, because the point is to see whether the adult reacts. Calm works best: say "okay, that was funny, now it is maths time."

A useful twist for a parent of a younger child: it is a number. "What is 6 times 7?" gets a laugh and a real answer, and a child who can say 42 is a child who has practised a fact.

Skibidi, and why a toilet got so famous

Skibidi Toilet began in 2023 as short animated clips, made with a free film tool, of toilets with human heads singing a looping song and fighting people who have cameras for heads. It is cartoon fighting, played for laughs, and children repeat the word as an all-purpose silly sound. "Skibidi" on its own means nothing. Words that people attach to it (skibidi rizz, skibidi Ohio) are the same joke stacked up: three silly words together are sillier than one.

Italian brainrot: Tralalero Tralala and friends

In 2025 a set of made-up animals with Italian-sounding names went around the internet: a three-legged shark in sneakers (Tralalero Tralala), a log with a bat that bangs at dawn (Tung Tung Tung Sahur), a crocodile that is also a bomber plane (Bombardiro Crocodilo), a ballerina with a cappuccino for a head (Ballerina Cappuccina). They are computer-made pictures with silly voices, and none is real. Kids trade them like Pokémon cards, and the Roblox game Steal a Brainrot turned the trading into a game.

The value for a parent: a child who can describe a creature, its powers and its name is doing the same thing as a child writing a story. That is the idea behind the Mash-up Maker described below.

Sigma, and the one word on this list worth a conversation

"Sigma" comes from a made-up ranking of men that some online self-help channels use ("alpha", "beta", "sigma"). Most kids who say it have never heard of the ranking. To them it means a person who does their own thing, and they use it as a joke: "what the sigma" is "what on earth." It is worth one calm conversation, because the original idea (that men fall into ranks and some are better) is not one you may want to teach. A good line to try: "I know the word is a joke to you. I only want you to know where it came from."

Words that are really about being kind or unkind

A few terms are used to tease: "NPC" (a person who acts without thinking), "cringe" (so awkward it hurts), "L" (loser). Children say them to each other the way earlier generations said "lame". The same rule applies as for any teasing: the word does not matter as much as the target. Ask who it was aimed at.

Some words have crude or sexual meanings that kids pick up from older children and videos. This page does not spell them out, and Peabody does not explain them to children: its Ask Peabody box declines, and the grown-up's log notes only the category, never the words. If your child uses a word that makes you wince, the three most useful questions are "where did you hear that?", "what do you think it means?" and "would you say it to Grandma?" You do not need to look it up in front of them.

Is brainrot bad for kids?

Nobody has shown that it harms a child's brain, and the word is a joke the kids made about themselves. The honest worry is time. Short videos are built to be scrolled, there is no natural end, and an hour disappears. Three habits help: pick the end before they start ("two videos, then we eat"), keep screens out of bedrooms at night, and give the silliness somewhere to go that makes something. A child who invents a creature, names it and tells a joke about it has turned watching into making.

What Peabody does about it

Peabody has a corner for the same energy, built so that it ends and cannot reach strangers. Silly Stuff is a wing of the Art Studio:

• Mash-up Maker. A child picks two things (a shark and a slipper) and Peabody draws them mashed together and names the result from their syllables ("Sharkaslippa!"). Younger children get compound words, middle grades get syllable claps, older children get alliteration titles and a rhyming couplet. The names are made by rules, not by an AI model, so each one is the same every time and costs nothing to make.
• Caption it. A funny picture and a caption to give it: the youngest choose the funniest of three, and third graders and up build one from a word bank and pick the end mark. Writing a punchline is writing.
• Joke book. Every joke of the day so far, read aloud with a button to tell it to someone. Peabody never listens through a microphone: the telling is to a real person.

None of it uses free text from a child, a real person's name or a picture of a real person, and every word a child can see passes the same word check as the rest of Peabody. See the Peabody guides for how the rest works.

Common Sense Media's reviews of YouTube channels and games are a calm place to check a specific show, and your child's school librarian is usually the best-informed adult in the building about what is going around. Read a story together when the screen time ends; the slang will still be there tomorrow.

Questions parents ask

What does 67 mean?

It means nothing. Kids say "six seven", often with their hands going up and down, because it is funny to say. It came from a song and from basketball video edits in 2025, and Dictionary.com picked it as its 2025 word of the year.

What does skibidi mean?

It means silly, cool or just loud. The word comes from a cartoon series about singing toilets, but kids use it as a nonsense word with no fixed meaning.

What is Italian brainrot?

Italian brainrot is a set of made-up animals with Italian-sounding names, like a shark in sneakers called Tralalero Tralala. They are computer-made pictures with silly voices, none of them real, and kids collect and trade them like cards.

What does sigma mean?

Kids use "sigma" for someone who does their own thing, and "what the sigma" for "what on earth". It comes from a made-up ranking of men used by some online channels, which is worth a short, calm conversation if your child uses the word a lot.

Should I ban brainrot?

Banning a joke makes it funnier. Limit the time instead: choose how many videos before they start, keep screens out of bedrooms at night, and offer something to make. Peabody's Silly Stuff is free through the end of 2026 and has no feed and no strangers.

How do I find out what a new word means?

Ask your child to explain it to you, then check a reference site you trust. Words that make you uncomfortable are a reason to ask where they heard it, not to search for it together.
