KYS means Kill Yourself.
The Full Answer
KYS is a slang abbreviation that stands for Kill Yourself.
If someone sends you a text or social media message saying kys, it means they think you have…
said or done something really stupid…
or that you have been an asshole.
It isn’t usually meant as an instruction to commit suicide…
unless you have been a complete asshole, of course.
Saying kys to someone is a flippant way of saying go fuck yourself or shut the fuck up.
