The exact recording behind this clip is not documented, so it is best treated as an anonymous German meme soundboard entry rather than a quote from a known show or film. The phrase itself simply means back to the Stone Age, and German-speaking creators have adopted it as a shorthand roast for anything hopelessly outdated. It circulates mainly through meme soundboards and short-form video edits, where its brevity makes it an easy reaction insert. Its staying power comes from that universality: every generation has its own version of the Stone Age.
