To be a target for death.
Also know as, "In the Hat."
In the old days when convicts wanted to kill someone, usually a stool pigeon, they would make five or six pieces of paper. Only one paper would have his name on it and each convict would draw a piece of paper from a hat or cap. If he got the paper with the name on it, he had to kill the victim. The mystery of it was that no one but the one who drew it knew who got the job.
