The phrase comes from colloquial Indonesian and Malay slang, where 'apa mau' is a direct way to ask what someone wants. As a short voice note style clip, it spread online through meme pages, group chats, and short video edits as a reusable reaction sound. Its popularity comes from its universality, anyone understands the annoyed tone even without speaking the language. Creators keep using it because it works as both a literal question and a comedic dismissal for absurd or out of context moments.
