The phrase itself is a common German expression for describing something that feels centuries out of date, which is why it works so well as a reaction sound even without a famous film, show or viral video behind it. On soundboards and in short-form edits, the clip is kept brief and reusable, so creators can reuse the same judgement again and again whenever a scene looks backward, inefficient or stuck in the past. Its appeal is the simplicity of the comparison: no context is needed to understand that whatever has just happened belongs to another era.
