The Rule is an acknowledgment of one's own mortality and is invoked as a means of avoiding activities, people, movies, organizations, books and TV shows that are very likely a total waste of time.

In essence, it means that each of us only have a finite number of summers left, and those summers aren't to be frittered away on meaningless crap.
