When the
will-they-
won't-they couple on a TV show finally gets together... and it ruins the show. (Derived from the 1980's TV show Moonlighting, whose ratings declined to the point of cancellation after the
main characters finally resolved their sexual tension)
"I really wish they'd just get together
already!"
"As much as I want that to happen, I'd hate for the show to be
ruined by the Moonlighting Curse."
"I guess you'
re right. The show won't be as much fun once the sexual tension is gone."
