How it's used

This expression carries a strong negative connotation, implying that the person possesses genuine intelligence or cleverness but chooses to apply it toward deceitful or antisocial behavior. It is frequently used by elders or parents to scold someone who is wasting their potential on petty schemes or dishonest shortcuts. Unlike simply calling someone a liar, this phrase highlights the irony of their wasted talent.

Examples

Common phrases

to be smart in a crooked way

Common mistake

Do not use this to describe someone who is simply intelligent or hardworking. It specifically requires the context of using one's brain for something morally questionable or counterproductive.
