20 Other Ways to Say “Bad”

The word “bad” is a simple and frequently used adjective to express something negative, undesirable, harmful, or of low quality — whether you’re talking about behavior, performance, outcomes, or general conditions. For instance, when someone says, “That was a bad movie,” they are sharing a clear, though basic, judgment about the quality of the film.
