moron

This term carries a heavy negative charge and is primarily used as a derogatory insult to attack someone's intelligence or judgment. It suggests a total lack of common sense or a failure to grasp obvious facts, often used in moments of frustration or mockery. Historically, the word functioned as a technical classification in psychology to describe a specific range of intellectual disability. Because of its transition from a clinical label to a common slur, it is now considered offensive and obsolete in medical or professional contexts.
