doomer

Those who suggest the likely return of the four horsemen of the apocalypse (famine, pestilence, war, and death) are more vocal than ever before despite being labeled Malthusian or just "doomer."

Doomers, meanwhile, are the nihilistic cousins of “Bloomers” and “Gloomers,” all three gradients of the same 20-something. Whereas Bloomers are well adjusted and Gloomers are depressed because they are not, Doomers have simply stopped trying. They are no longer pursuing friendships or relationships, and get no joy from anything because they know that the world is coming to an end.

Are not the heavens doomers of men's deedes?
