The phrase is Romanian, roughly asking what has gotten into someone and why they are acting that way, and online it has settled into use as a reusable scolding reaction. Clips like this circulate on soundboards and in short video edits because the emotion is clear even for viewers who do not speak the language. Its longer running time sets it apart from a quick shout, giving editors a sustained outburst to match a scene that keeps getting worse, which helps explain its repeat use in memes.
