The Word of the Day from The Zombie Cause Dictionary by Doc Lucky Meisenheimer is:
Barbara idiom. A histrionic female who is non-functional in the presence of zombies; derived from the movie, Night of the Living Dead. Barbara was a catatonic woman who was totally worthless almost throughout the entire movie. It was a welcome relief to see the zombies finally get her.
Example: “The best thing to do with a Barbara is to dump her against the door. It helps barricade the door and she screams a nice alarm when the door starts to open.”
