Kto to napisał is a Polish phrase that spread online as a ready-made reaction rather than as a quote tied to a confirmed film or show. Polish-speaking users began dropping the short voice clip under screenshots, reposts and comment threads where the writing was confusing or unintentionally funny. From there it moved into meme edits and soundboards, where the foreign wording became part of the appeal for wider audiences. It remains popular because the question is universal and the short runtime makes it easy to reuse.
