Teen Text Slang and Codes: A Parent's Guide (2026)
Almost every "secret teen text code" list you will find is the same list. It has been copied from site to site since about 2008, and it is padded with acronyms no teenager has typed in a decade — CD9, P911, NIFOC. Meanwhile it marks 💀 as sinister when it means "that was funny," and omits unalive, which is current, widespread, and genuinely worth knowing.
This guide is organised differently. Everything below is sorted into three groups: worth asking about, worth knowing, and benign or extinct — including the entries that only ever appear on parent websites. The goal is not to make you more alarmed than the evidence supports. It is to help you tell the difference between a child being fourteen and a child in trouble.
The Short Version: What Actually Matters
If you read nothing else, these are the terms that carry real signal in 2026:
| Term | Means | Why it matters |
|---|---|---|
unalive |
Kill, die, suicide | Invented to dodge automatic moderation. Current and everywhere. |
KYS / KMS |
Kill yourself / kill myself | Often hyperbole. Sometimes not. Pattern matters more than one use. |
LMIRL |
Let's meet in real life | The single highest-risk acronym, if it comes from someone met online. |
seggs / corn |
Sex / porn | Deliberate misspellings, same moderation-dodging reason as unalive. |
ana / mia |
Anorexia / bulimia, personified | Pro-eating-disorder community shorthand. A strong signal. |
grippy sock vacation |
A psychiatric hospital stay | Usually gallows humour. Still a signal. |
SH / edtwt |
Self-harm / eating-disorder Twitter | Tags used to find those communities. |
Seven terms. Not two hundred. The long lists are long because length looks like thoroughness, not because two hundred codes are in use.
Why Most Slang Lists Are Wrong
Three failures repeat across nearly every article on this topic, and knowing them will save you a great deal of unnecessary worry.
They are recycled. CD9 ("code 9, parents are around"), P911, NIFOC, 53X, CU46 — these appear on virtually every list and are essentially extinct. They come from an era of shared family desktops and MSN Messenger, when a child needed to warn a friend that a parent had walked in. Teenagers now have private devices. They do not type a code; they lock the screen.
They misread benign things as sinister. 💀 and ⚰️ mean "I am dying of laughter." 🧢 means "that's a lie." 🐐 means "greatest of all time." Parent lists routinely present these as coded and alarming. Getting this wrong has a cost: confront a child about a skull emoji and you have told them, credibly, that you do not know what you are talking about — which makes the next conversation harder.
They flatten risk. A list that gives bet (meaning "OK") the same visual weight as LMIRL is not helping you prioritise. Most slang is just language. Teenagers have always had their own vocabulary; that is developmentally normal and not a warning sign.
Group 1: Worth Asking About
These carry genuine signal. Seeing one is not proof of anything, but it justifies a conversation.
unalive, unalived. Substitutes for kill/die/suicide, invented because TikTok and YouTube suppress the real words. Its existence is a moderation artefact, not a secret code — but it means discussion of death and suicide is happening in a vocabulary designed to be un-searchable, including by you.
KYS, KMS. "Kill yourself" and "kill myself." Frequently hyperbole — "KMS, I bombed that test" is closer to "ugh" than to intent. What matters is frequency, direction (is it aimed at your child, or from them?), and whether it clusters with other signs. Our guide to teen phone addiction signs covers reading patterns rather than incidents.
LMIRL. "Let's meet in real life." If it comes from an existing school friend it means nothing. If it comes from an account your child met in a game or a Discord server, it is the single most important thing on this page.
ana, mia, edtwt, SH. Pro-eating-disorder and self-harm community shorthand — Ana for anorexia, Mia for bulimia, both personified as friends. These are not casual usage. They indicate a child is inside a community that reinforces the behaviour, which is a different and more serious situation than a child struggling alone.
Sexual-content acronyms in current use: DTF, TDTM, S2R ("send to receive"), sugar pic, thirst trap. Of these, only thirst trap is genuinely mainstream and mostly harmless. S2R in particular indicates photo trading, which is where image-based abuse starts.
plug. Someone who supplies something, usually drugs. Paired with 🔌.
Group 2: Worth Knowing, Usually Fine
These come up constantly and are almost always ordinary teenage life.
opp — enemy, rival, someone you are against. Mostly ordinary friction-talk. gyat — an exclamation about someone's body; very common, usually joking. smash, FWB — casual sex and friends-with-benefits; a fourteen-year-old using them is usually performing worldliness rather than reporting events. looksmaxxing, mewing, sigma — appearance and social-hierarchy vocabulary out of the manosphere. Not dangerous in themselves; the surrounding communities can be, and it is worth knowing which creators your child is watching.
Group 3: Benign — Do Not Panic About These
cap / no cap (a lie / seriously), bet (agreed), sus (suspicious), mid (mediocre), slay and ate (did well), rizz (charisma), delulu (delusional, usually self-mocking), bussin (very good), IYKYK, FR / ONG (for real / on God — emphasis), NPC (unoriginal person), glazing (sucking up), ratio'd (publicly out-replied), cooked (in trouble or exhausted), yapping (talking too much), aura (coolness, gained or lost).
None of these are codes. They are dialect, and every generation has had one.
Group 4: Extinct — But On Every List
Included so you can recognise them as noise rather than assume the list you found is current.
CD9 / Code 9, P911, POS / PAW / MOS (parent over shoulder), NIFOC, GNOC, IWSN, 53X, CU46, ASL. If an article presents these as urgent 2026 intelligence, it was assembled from other articles rather than from any real observation, and you should discount everything else on it accordingly.
What to Do When You Find Something
The instinct is to search the term, decide what it means, and confront. That order is usually wrong.
Ask first. "I saw this and I don't know what it means" is a genuinely disarming opener, and it is true. A teenager explaining their own vocabulary is a conversation. A parent arriving with a printout from a parenting site is an interrogation, and it teaches them to move the conversation somewhere you cannot see.
Look at pattern, not incident. One dark joke is a dark joke. A change in volume, tone, sleep, or who they talk to is the actual signal. Slang is a lagging indicator of things you can usually see in behaviour first.
Match the response to the finding. bet needs nothing. LMIRL from a stranger needs immediate attention. Treating those the same is how parents lose credibility.
Know when it is beyond a conversation. If you find self-harm or eating-disorder community content, that is not a discipline matter and a filter will not fix it. It is a moment to involve your GP or paediatrician. If you find sexual content involving your child, our guide on what to do when a child sees porn covers the first steps.
An Honest Note on Where Filtering Helps
We make parental control software, so it is worth being straight about what it does and does not solve here.
Slang lives in messages — texts, DMs, Discord, Snapchat. A website filter does not read messages and will not surface any of this. If message-level visibility is what you want, a monitoring product such as Bark is the honest recommendation, and our Bark vs Covenant Eyes comparison explains what that model does and costs.
Where filtering does help is upstream: most of the material that shapes this vocabulary — the pro-ED communities, the manosphere creators, the sites where a stranger becomes a contact — arrives through a browser on an unrestricted device. Controlling what a younger child's computer can open reduces how much of it reaches them in the first place. That is prevention, not detection, and it works better the younger the child is. For a sixteen-year-old, conversation is the tool; for an eight-year-old, an allowlist is.
Frequently Asked Questions
What are the most important teen text codes for parents to know?
unalive, KYS / KMS, LMIRL, seggs / corn, and the eating-disorder shorthand ana / mia / edtwt. Everything else is either ordinary slang or an acronym recycled from the 2000s.
Is 💀 a warning sign?
No. It means something was extremely funny — the same as ⚰️. It is the most commonly misread emoji on parent websites. See our emoji meanings guide.
My child uses KMS all the time. Should I be worried?
Usually it is hyperbole for frustration. Worry about frequency, whether it appears alongside withdrawal or sleep changes, and whether it ever appears without a trigger. If you are unsure, ask directly — asking a child about suicidal thoughts does not plant the idea, which is a well-established finding.
How do I keep up with teen slang?
You cannot, and trying is the wrong goal. Vocabulary turns over every few months. Knowing the handful of terms that carry real risk, plus an open enough relationship that your child will explain the rest, beats memorising lists.
Should I read my teenager's messages?
That depends on their age and on whether you have a specific concern. Covert monitoring of an older teenager, if discovered, generally costs more in trust than it returns in information. If you do it, telling them it is happening is both more ethical and, in practice, more effective.
