The phrase is Brazilian Portuguese slang, with crlh being a shortened written form of a common swear word used for emphasis online. Short shouted audios like this circulate widely through WhatsApp groups, meme pages and short video edits in Brazil, where a recognisable outburst can be reused for endless new situations. Its appeal is less about a specific source and more about the delivery, which creators borrow whenever a scene needs instant comic frustration, disbelief or mock outrage without any setup or explanation needed.
