The phrase is German for a self-styled doer and fighter who pushes through, and as a sound it circulates mainly as a short reaction clip for determination rather than as a line tied to a known film, song or television moment. Its appeal online comes from the contrast between the bold self-description and everyday situations, so creators reuse it whenever stubbornness or finishing something becomes the joke. It keeps appearing in short-form edits where a quick motivational beat is needed.
