The infamous tumblr crash of December 12, 2012, is the day when tumblr was down for hours with no warning. Lots of "MY FEELS" and "ALKAFELFJAFJEWLAKJKA" resulted from this. People believe this is really the end of the world, because it happened on a triple date. Some also think that it was also another social experiment conducted by Cole Sprouse.
Sometime in the near future:
-Hey Liz, what are you doing?
-Nothing. I think there might be another tumblr crash of 12/12/12 going on. What will I do with my life? MY FEELS.
