The phrase is Polish and translates roughly to a blunt warning that someone is about to be hit on the head, which explains its use as an exaggerated, joking threat rather than a serious one. Its original speaker is not documented in the clip itself, so online it circulates mainly as a short soundboard sound rather than as a quote tied to a famous scene. Polish-speaking creators reuse it in pranks, gaming clips and reaction edits because the tone is instantly recognisable, and its one-and-a-half-second length makes it easy to drop into a fast cut without interrupting the action.
