Little reliable information is available about the origin of Fussekks, and the name itself appears to be a user generated soundboard label rather than a title from a known film, song or show. Clips like this usually circulate because the timing is useful, not because listeners recognise a source. It has found a small audience as a flexible reaction sound, shared for quick edits, group chats and short form posts where a brief, unexplained audio hit can stand in for confusion, surprise or a deliberately random joke without needing any setup beforehand.
