Dead Man Walking

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).

Does not have anything to do with The Undead but is often used that way Just for Pun. Compare Your Days Are Numbered, Who Dunnit to Me?, Incurable Cough of Death, Doomy Dooms of Doom.

Invoked by Dead Star Walking. Sometimes used to describe a state in a game that's Unwinnable by Design.

 * Stephen King's The Green Mile has the warden Percy Wetmore, who tries to carry out the traditional callout as he leads John Coffey to his cell in E block.

 * Literally the title of a Warhammer 40,000 novel, showcasing the incredibly dour Death Korps of Krieg as they battle the implacable Necrons. The title comes from the fact that the Kriegers have no moral compunction against sacrificing their own men to kill the enemy, and are all drilled to have no dreams, aspirations, or visions of the future beyond service in the Imperial Guard—and their inevitable death. They are so cold and emotionless as to creep out their fellow Guardsmen.
 * It helps that all Kriegers are cloned.
 * Another WH40K example: Within the Night Lords legion there was a practice of placing a suspended execution upon legionaries who warranted death, but were too valuable to be executed at present. Their gauntlets were painted arterial, or "sinner's" red and their lives continued at the whim of their primarch.
