As an idiom, the phrase "dead man walking" is most infamous as a call-out once traditional in American prisons; when the wardens would lead a man on Death Row down the hall, declaring "Dead man walking! Dead man walking here!" Dead Man Walking means Your Days Are Numbered and you and/or the people around you know it. Now that prison wardens no longer use it (least not where they can be noticed), modern use of the term broadened somewhat to other types of doom, even benign "doom" such as losing a job (which may actually be the original meaning, but so far no one's been able to trace it conclusively).
Sometimes, when the police are investigating a "murder" without a body, they find the so-called "victim" alive and well and the police utter "Dead Man Walking?"
Invoked by Dead Star Walking. Sometimes used to describe a state in a game that's Unwinnable by Design. Not to be confused with Dead Character Walking, which describes a video game glitch where the player still has control over a dead character.
