The May 21, 2011 Rapture meme stems from a massive media campaign led by American Christian radio host Harold Camping, who predicted the world would end on that specific date. After billboards and flyers spread the warning globally, the day passed without incident, leading to a surge of internet mockery and 'survivor' parodies. It is commonly used to poke fun at false predictions, cult-like obsession with doomsday dates, or the general feeling of anticlimax when a hyped event fails to occur.
