Das geht doch nicht is a common German expression meaning that something simply will not work or is not acceptable, which is why it travels so well as a reaction sound even for listeners who do not speak German. Online, short spoken phrases like this are often clipped from television, streams and everyday speech and reused in memes, reaction videos and short-form edits, where a single emphatic line can replace a longer explanation. Its brevity makes it easy to drop into a cut, and its frustrated tone gives an instant verdict on whatever has just happened.
