a term used as an excuse to do whatever you want because on December 21, 2012 the world is supposed to come to an abrupt end
Jeremy: I wish i could go to the lake tomorrow but i have to work.
Sarah: Who gives a shit! the world is going to end!!
Tammi: I wish i could go on vacation but i just can't afford it.
Sarah: Just spend the money... the world is going to end
lets be honest... if there world were going to end tomorrow would it really matter if you ran that red light? would it matter if you spent all your money that was supposed to be for monthly bills on hookers and blow? Just do whatever you want - who gives a f*ck...the world is going to end!!
