A zombie walk (also known as a zombie mob, zombie march, zombie horde, zombie lurch, zombie shamble, zombie shuffle orzombie pub crawl) is an organized public gathering of people who dress up in zombie costumes. Usually taking place in an urban centre, the participants make their way around the city streets and through shopping malls in a somewhat orderly fashion and often limping their way towards a local cemetery or other public space (a series of taverns in the case of a zombie pub crawl).

Promoted primarily through word of mouth and online message boards, zombie walks are an underground activity. During the event participants are encouraged to remain in character as zombies and to communicate only in a manner consistent with zombie behavior. This may include grunting, groaning and slurred, moaning calls for ‘brains’. It should be noted that zombie behavior is a hot topic of debate. Purists who draw their definitions from the original Living Dead films will claim that a zombie would never have the ability to call for ‘brains’ and furthermore that a zombie needs only living or freshly killed flesh for its sustenance, and not the brain in particular.

An advanced technique to heighten interest and realism, some zombie mobs will “eat” victims to create new zombies, in sight of onlookers.  The better coordinated zombie mobs will establish a route and an easily recognizable signal, so that other participants can plant themselves, appearing as an otherwise ordinary human, along the route in old, tearable clothes, and as the mob shambles along it can discover and devour new victims. As the zombies surround the new victim to loudly feed, concealing him or her from witnesses’ view, they tear clothes and quickly apply greenish makeup and fake blood, to create a new zombie, who then shambles along with the ever-expanding pack to find new victims.
