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.

A virus that does not actually exist, but is a possible mutation of an existing virus, or an entirely made up virus that can possibly exist without defying medical knowledge. Examples of fictional virus include Lyssavirus X and Filonecrosis. The movie entitled "Outbreak" was a good example of a fictional virus.
Despite the fact that they don't exist, it's important to be prepared for fictional viruses, since viruses are known to mutate to more potent forms all the time.

Any situation whereby a number of zombies, usually viral zombies, have come to exist in a given area and are threatening the local population. There are different classifications of outbreak, from small isolated incedents to a worldwide explosion of zombies. To counteract this problem, there are zombie survivalist groups, such as OZORT, that work to allow people to discuss what to do in the event of various stages of zombie outbreak.
There was a small zombie outbreak in Cambodia a few years back, but the local millitary contained the issue before it became a crisis.
