“Democalypse” (democracy + apocalypse) was the catchphrase that Comedy Central’s The Daily Show applied to the 2012 U.S. presidential election. “Democalypse 2012” aired on June 11, 2012, followed by many other similarly titled segments.
 
The term “democalypse” had been infrequently used before 2012. “Signs of the Democalypse” was on Twitter on January 25, 2010.

More Moments of Zen, More Indecision Theory

Pg. 2:
As for “indecision theory,” fans of The Daily Show are familiar with their longstanding election coverage tag: “Indecision 20_” (there having been Indecisions 2000, 2004, 2008, and 2012, plus midterm Indecisions 2002, 2006, and 2010—although “Democalypse 2012” seems to have proved a more popular label, at least up until Stewart and Colbert’s joint election-night coverage).
