1. Jump the shark is a term to describe a moment when something that was once great has reached a point where it will now decline in quality and popularity.
Origin of this phrase comes from a Happy Days episode where the Fonz jumped a shark on waterskis. Thus was labeled the lowest point of the show.
2. It is the precise moment when you know a program, band, actor, politician, or other public figure has taken a turn for the worse, gone downhill, become irreversibly bad, is unredeemable, etc.; the moment you realize decay has set in.
Tom Cruise jumped the shark the moment he jumped Oprah's couch.
