The phrase comes from everyday Thai slang, where 'mor oy' is an informal, joking term for pubic hair, and the full line is phrased like a deadpan public announcement. It spread as a short shareable audio clip on Thai social media and soundboards, passed around less for any single original video than for the reaction it gets. Its 1.7 second length made it ideal for reposting, remixing into edits and triggering in live chats, and it remains used as a quick, recognisable Thai prank sound rather than a song or film quote.
