You're scrolling through your teenager's social media — maybe casually, maybe because something felt off. The messages look like they were written in a foreign language. "No cap this guy is sus." "She got ratio'd." "Plug pulled up, it was bussin."
Most teen slang is exactly that — slang. Creative, funny, totally harmless. But hidden inside the same streams of messages and DMs are codes that aren't. Drug transactions. Sexual solicitation. Real distress dressed up as a joke.
This guide covers 50+ terms and emoji codes across three categories: everyday slang you can mostly scroll past, coded language worth understanding, and the emoji shorthand that parents are consistently blindsided by. Every entry has a risk rating so you can focus your attention where it actually matters.

Why Teens Use Coded Language Online
Before diving in, it helps to understand why this language exists. Teen slang isn't new — every generation has had it. What is new is the speed at which it spreads. A phrase coined in a TikTok comment on Monday can be in millions of group chats by Friday.
According to Pew Research, 95% of teens have access to a smartphone and 35% say they are on at least one social media platform "almost constantly." That's a lot of language being invented and circulated out of adult view.
Teens use slang for a few core reasons:
- Belonging — shared language signals you're part of a group
- Speed — abbreviations and codes are faster than full sentences
- Privacy — keeping conversations incomprehensible to parents and teachers
- Cultural participation — using the right words signals awareness of memes, games, and creators they follow
Most of it is completely innocent. The goal of this guide is to make sure you're not caught off-guard by the small percentage that isn't.
How to Read This Guide
Every term below is rated on a three-level scale:
Part 1: Everyday Slang (Mostly Harmless)
This is the bulk of what your teen is saying online. Most of it changes every six months, mostly just means you're out of the loop, and requires zero action from you.
Part 2: Coded and High-Risk Language
This section is worth reading carefully. Some of these terms are used openly and could mean nothing in isolation. But in combination — or alongside unknown contacts, late-night activity, or sudden secrecy — they matter.
Part 3: Emoji Codes Parents Are Being Blindsided By
Emojis have a second language. Dealers, predators, and teens use them specifically because they look innocent to adults — and because they evade platform detection algorithms. The following combinations are documented by the DEA, law enforcement agencies, and digital safety researchers.
The 5 Terms That Need a Conversation Right Now
If you take nothing else from this guide, know these five.
1. KMS / KYS
"Kill myself" and "kill yourself" are used so casually online that many teens don't register them as serious. But research from The Lancet and others consistently shows that normalising this language has a measurable effect on teen mental health — and some uses are genuine cries for help dressed up as jokes. If your child uses it frequently or outside a clearly joking context, have a direct, non-punishing conversation. Resources: Beyond Blue (AU), Samaritans (UK), 988 Lifeline (US).
2. CD9 / P911
If you see this in your child's chat, they are actively hiding a conversation from you in real time. This isn't about punishment — it means there's a conversation happening they feel they can't let you see. That's the starting point for a calm, honest discussion about what's going on and why they felt they needed to hide it.
3. GNOC / "Wanna trade?"
These phrases are used almost exclusively in sexual solicitation — often by adults targeting minors. "Get Naked On Camera" is frequently accompanied by flattery, pressure, or threats. "Wanna trade?" is one of the most common opening lines in image-based exploitation. If either appears in your child's DMs from someone they don't know in person, contact NCMEC CyberTipline (US), CEOP (UK/AU), or your local police.
4. Pressed / Blue / Perc
Counterfeit pills bought through social media — sold as Xanax, Adderall, or Percocet — are now the leading cause of teen overdose deaths in the US and are rising globally. One pill can be lethal. If you see pill language alongside unknown contacts or requests for money, treat it as urgent. Contact SAMHSA (US) or Talk to Frank (UK).
5. Sigma + Based + Red Pill (in combination)
Individually, these words are fairly harmless. Together — especially when combined with content glorifying dominance, dismissing women, or framing vulnerability as weakness — they can signal exposure to incel or manosphere ideology. Netflix's Adolescence brought wide attention to how quickly these ideas spread through teen boys' group chats. If your son is using these terms heavily, explore what content he's watching and open a conversation about it.
