Definition
An official record or file indicating that a prisoner is mentally ill.
How it's used
Originally referring to specific medical records for inmates in Hong Kong prisons, this term has evolved into a common piece of slang used to describe someone who is acting foolishly or behaving in a way that suggests they are not in their right mind. It carries a strong sense of mockery and is often used as a rhetorical question to challenge someone's questionable decision making. Because it touches on mental health, it is considered insensitive and should be used with caution outside of very informal settings.
