The phrase ya metnak comes from Egyptian Arabic slang, where it works as a crude insult directed at a man. No single film, show or original recording is reliably credited for this short clip, which instead spread as a standalone sound through Arabic meme pages, group chats and soundboards. Its short length and forceful delivery made it easy to reuse as a reaction, and it remains popular because the anger in the voice reads as comedy even without understanding every word of the phrase being shouted loudly.
