The act of reviving or perpetuating a once relevant TV program, movie franchise, etc. that has already passed its peak (i.e., jump the shark
) in the selfish hope of getting more money or compensation (e.g., fame) out of it. Ultimately, the perpetrators/propagators get a nasty surprise when they find out the "shark" is no longer fit for "humping".
"Did you hear they're making a film about golden retriever puppies that play rugby? It's called 'Scrum Buddies'."
"Wow, those guys sure are humping the shark with all the 'Buddies' movies."
