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
He is always smart in the wrong way, only thinking of underhanded tricks.
You are so smart, why do you use your wits for cheating people?
