What does "low-key" mean in slang?

The adverb "low-key" means subtly, mildly, or in a quiet or understated way. The structure comes from "low," implying reduced intensity, and "key," referring to level or prominence. It is informal slang used to express something without strong emphasis or publicity, such as "I low-key like it," meaning the feeling is real but not strongly or openly expressed.
