KMS originates from the Internet and gaming culture, which is in the form of dark humor or exaggerated emotional response. Originally found in forums and chat rooms, it quickly spread to mainstream platforms such as Twitter, TikTok, and Instagram. While mostly joking, the meaning developed and attracted attention due to concern for mental health. Today, it sits in a gray field, used for both humor and serious expression. Awareness of mental health has made people more cautious about this slang.
