The phrase comes from everyday Hindi and Hinglish slang, where 'nich' is used to describe someone considered low, mean or lacking character. Online, the line circulates as a short reaction sound rather than as a clip tied to one famous film or show, which has helped it travel across meme pages, reaction edits and short-form videos. Its appeal is its directness: listeners do not need context to grasp the judgement, so creators reuse it whenever a moment needs a blunt, instantly understood insult.
