There is no widely documented source for this short German phrase, and it circulates online mainly as a compact, reusable sound rather than as a quote from a named film, show or song. Its appeal comes from its simplicity: two opposite directions in one short clip are easy to recognise, easy to caption and easy to reuse across languages. That makes it a handy shorthand in travel content, gaming clips and meme edits, where a quick left-right decision can carry the whole joke without extra explanation.
