The phrase is everyday Hindi slang, with aadmi meaning man and chutiya hai amounting to is an idiot, so the meaning needs no explanation for its main audience. Clips using the line circulate as short shareable audios and meme sounds rather than as a formal recording, passed around for the reaction alone. Its popularity comes from how directly it sums up disbelief at foolish behaviour, letting creators add a familiar desi voice of judgment to videos, chats and edits without recording their own line.
