Definition & Meaning of "kill myself"in English

What does "KMS" mean in internet slang?

The structure is an initialism standing for "Kill Myself." It is used hyperbolically and informally to express extreme frustration, embarrassment, or annoyance over a minor or everyday situation, not as a literal statement of self harm. People typically type "KMS" after making a silly mistake, losing a game badly, or experiencing secondhand cringe, such as "I tripped up the stairs in front of everyone, KMS" or "KMS I forgot to save my game after three hours." Because of its sensitive nature, many online spaces discourage or flag the term to avoid trivializing serious mental health issues.
