stupid person

Not very bright

A stupid person is someone who lacks intelligence, common sense, or good judgment.

The phrase is straightforward and mildly insulting—less crude than idiot or moron, but still dismissive: Don't be such a stupid person.

Often used in frustration rather than clinical assessment.
