Noun (zee day): A term probably coined by Max Brooks which refers to the war between zombies and mankind. Derived from the word D-Day, which is a British term used to refer to a variable day on which a combat attack or operation is initiated. Z-Day is marked by a sudden attack on mankind by zombies, which will lead to a widespread zombie outbreak. There are a number of zombie survivalist groups worldwide (largely in the US, UK, and Canada), that are already planning what to do when this day comes.
Z-Day will catch mankind completely off guard, and the lack of preparation will lead to countless casualties.
