Hold nu kæft is a common Danish expression that roughly translates to shut up now, and adding Frederik makes the line feel personal and specific. That specificity helped the clip spread as a Danish meme sound on soundboards and in short video edits, where the name becomes part of the joke even for listeners who do not know any Frederik. It remains popular because the delivery is universal: frustration, volume and timing need no translation, so the clip works in chats, streams and reaction videos far beyond Denmark.
