When one's penis transitions from an erect to a flaccid state.
Dave, while watching an exercise show that he finds arousing, suddenly sees his television program switch to a black screen that informs him to call his local cable provider in order to resolve an issue. At that moment, Dave realizes that he failed to pay his cable bill and will not be able to watch his exercise show any time soon. Deeply saddened, Dave turns to his dog, Winston, who happens to be staring at him. Dave informs Winston that "Olympus has fallen."
