Self-harmIs “KMS” something to worry about? More Self-harm terms
KMS
Risk flagKill myself — a coded way to express suicidal ideation or express extreme frustration.
How kids use it
Common across TikTok, Instagram DMs, Snapchat, and text; used by ages 10-16, often appears in joke contexts but can indicate genuine distress.
Treat "KMS" as real until you know otherwise. Kids often talk about distress in coded or joking language first — the cost of taking it seriously and being wrong is a slightly awkward conversation; the cost of dismissing it and being wrong is much higher.
- Ask directly and calmly. Naming it doesn’t plant the idea — that’s a myth.
- If there’s any indication of intent: the 988 Suicide & Crisis Lifeline (call or text 988) is free and 24/7.
- Loosen the late-night phone window — distress content hits hardest alone at 2am.
