To create an episode of a television show or film in a franchise that is SO BAD that it not only damages the reputation of the series itself, and the reputations of all involved in making it, but it even damages the genre that the show was created in. Think 'jump the shark' or 'nuke the fridge' but x10: this is the ultimate nadir for creative artworks. The term derives from a ludicrous episode of the long-running science-fiction series 'Doctor Who' called 'Kill The Moon' (broadcast October 4, 2014) in which Earth's Moon turned out to be a giant dragon's egg that hatched and was then immediately replaced by another Moon: presenting a completely unbelievable version of science, this episode is considered by many to be the worst science fiction programme ever screened in the history of television. Past tense: killed the moon.
Joe: Hey, what did you think of the new Star Wars film 'The Last Jedi'?
Mike: O-M-G, that film was so bad - it sure did kill the moon!
