1. A person who makes up the gulliable minority of "Christians" who believe(d) in the May 21, 2011 rapture prophecy. This also includes Harold Camping himself, since he made the (failed) prediction in the first place.
2. Someone who lacks the ability to think for themselves and will blindly follow any doomsday propaganda claims they hear from the news or random people.
3. An embarassment to the human race.
Rapturefag: "MAY 21, 2011 WILL BE THE DAY OF RAPTURE! HAROLD CAMPING PREDICTED IT AND I BLINDLY FOLLOW HIS TEACHINGS BECAUSE I LACK A BRAIN TO THINK FOR MYSELF. REPENT NOW WHILE THERE IS STILL TIME!"
