This is the new term for when a
television series runs out of new material and begins making ridiculous subplots that inevitable lead to the downfall of the
show. Previous generations have called it "jumping the
shark" after a bold move by the Fonz.
The
prime example of this was in an episode of Lost called "Tricia Takanawa is dead", where the climax of the episode was when a
titanic man named Hurley drove a
broken VW hippy van down a hill for no apparent reason.
"Man that episode reminded me of when Lost got pushed downhill in a hippy van lol."
