The phrase is the Danish version of the 'that's what she said' joke, literally translating to 'she said that yesterday too', and it has been a staple of Scandinavian banter long before it reached soundboards. This particular clip looks like a homemade voice-recorder recording rather than a line from a film or show, so its exact origin is unclear. Short reaction clips like this spread through group chats, stream highlights and meme edits, where a native punchline in Danish lands harder with local audiences than the English original ever could.
