Über diesen Sound
This is a slowed-down, louder take on the single-word bruh reaction, stretched out over about two and a half seconds so the flat, unimpressed delivery lands even harder. It feels weary, blunt and deliberately overdone, like someone has heard the same nonsense one too many times and can only answer with a long, heavy sigh of a word.
