The phrase is everyday Norwegian, literally inviting everyone to sing together, which explains why the clip travels well even for viewers who do not speak the language. Its meaning is clear from its cheerful, communal tone and it has found a second life online as a reusable cue for singalongs, karaoke jokes and musical reveals. Rather than being tied to one specific performance, it works as a flexible meme sound that signals a song is coming, sets up an awkward pause, or turns an ordinary group moment into a small theatrical event.
