stands for impending zombie apocalypse. it is a theory that in some point in the not too distant future the dead will reanimate and spread over the world in months, weeks or even days leaving very few if any survivors. many movies video games and books have plots revolving around an IZA, some like dawn of the living dead cover the beginning, others like zombieland cover the aftermath.
