What does "brain-dead" mean in slang?
The term "brain-dead" means acting extremely thoughtless, slow, or unintelligent, often due to fatigue, distraction, or poor judgment. The structure is a metaphor where "brain-dead" exaggerates lack of mental activity, not a literal medical condition. It is informal slang commonly used in everyday and online speech, usually as a harsh criticism of careless or nonsensical behavior.
