The phrase points to SFO, the Danish after-school care where children spend time after classes, and the 'be like' format is a familiar online shorthand for acting out a stereotype for comic effect. On short-form video and meme pages, that combination turns an everyday school setting into an instantly readable joke, even for viewers who only recognise the energy rather than the specific place. Its appeal is local and relatable rather than tied to a famous film or song, which is why it circulates mainly as a niche in-joke among Danish school-age viewers and their friends.
