What does jump the shark mean?

Noun (1)

— jump the shark
: to undergo a significant change for the worse that decisively marks the point at which a period of success, excellence, or popularity ends (as for a TV series) and an unrecoverable period of decline begins

The phrase jump the shark derives from a 1977 episode of the American TV series “Happy Days” (1974–1984) in which the program's most popular character, Fonzie, jumped over a shark while waterskiing in his trademark leather jacket. Some years later that episode came to be widely identified as marking the beginning of the iconic show's decline.
