Shop-ocalypse means: This term is used to refer to the upcoming shop-ocalypse on the 22nd December 2012. If the world does not end on 21 December 2012, as predicted by the Mayans, people will head out to Christmas shop en masse in search of the items they need. In the chaos that ensues, this will result in thousands of people being killed. This will be known as the “shop-ocalypse” of 2012. (in Community Dictionary, added by Stenopaeic)
