KYS
An abbreviation for "kill yourself" used as a directed, harmful harassment phrase toward another person.
By Cal Hewitt, Gen X · Researched from public sources ·
What it actually means
KYS is second-person imperative language aimed at someone else, unlike first-person KMS. It may be typed as a supposedly ironic insult in gaming or social-media conflict, but its register is still directed self-harm harassment and it is not acceptable. It can cause real harm and should be reported rather than repeated or treated as banter.
See the quick definition in the KYS dictionary entry.
Where it came from
KYS is a transparent initialism for an English imperative that spread through informal online writing. No credible historical account establishes one coiner, first post, exact year, or originating platform, so claims assigning it to a particular community would be speculation.
No single person is credited, the origin is loosely attributed.
Where it's popular
English-language online conflict spaces, including social-media comments and game-chat environments, rather than a documented geographic region.
There is no reliable country-level prevalence data or defensible single-community origin. The relevant documented context is cyberbullying and online harassment.
How it caught on
- Texting and internet-chat eraThe initialism circulated as compressed written harassment; a first documented use or coiner is not established.
- Social-media and game-chat eraShort, repeatable abbreviations made it easy to carry harmful directed language across online conflict spaces.
- Current online-safety guidanceStopBullying.gov advises targets of cyberbullying not to respond or forward messages, to save evidence, block the sender, and report the abuse.
Common mix-ups
KYS is not harmless trash talk or a synonym for ordinary criticism. It is directed self-harm harassment, even when the sender claims it was a joke; because demonstrating the phrase as a usage example would reproduce abuse, this page intentionally has no usage examples.

Questions people ask
What does KYS stand for?
It stands for "kill yourself." It is a directed self-harm harassment phrase toward another person.
Is KYS acceptable as a joke?
No. A claim of irony does not remove the directed harmful content or its potential impact.
What should I do if someone sends me KYS?
Do not respond to or forward the message. Save evidence, block the sender, and report it to the platform; StopBullying.gov recommends these steps for cyberbullying. Seek support from a trusted person. If there is immediate danger, contact local emergency services; in the United States and its territories, 988 is available 24/7.
Why might a platform restrict or remove this language?
Platforms commonly moderate content involving self-harm and harassment. Users sometimes create coded alternatives in response to actual or perceived moderation, but a code does not make directed abuse acceptable.
The key grammatical difference from KMS is the pronoun: KYS directs the phrase at another person, which changes it from ambiguous first-person language into harassment.
