The phrase is Kansai-dialect Japanese: 'douiushi yanen' is the rough, confrontational way of asking 'what do you mean', and 'koraa' is a snarled 'hey you'. No single anime, show or creator can be confirmed as this recording's source, so it is best treated as a reaction meme that caught on through soundboards and video edits. As a shout meme it thrives wherever exaggerated anger is the joke, from anime compilations to gaming clips. Its staying power is versatility: any outrage reaction, from a bad take to a rigged game moment, lands harder with Kansai fury behind it.
