How it's used
This expression carries a strong negative connotation of arrogance and condescension. It is specifically used to describe someone who pretends to be an expert or gives unsolicited advice to show off their perceived superiority. Unlike simply being smart, this implies the person is actually lacking knowledge or is being insufferable in their delivery.
Examples
He is always acting like a know-it-all, it is really annoying.
Related words
Common mistake
Do not confuse this with simply being smart or knowledgeable. It is strictly used to criticize someone's attitude, so using it to describe a genuine expert who is being helpful would be offensive.
