How it's used
This idiom is used to describe someone who is acting suspiciously because they are hiding a wrongdoing or a secret. It carries a strong implication of guilt and anxiety, often suggesting that the person is afraid their past actions will be exposed. It is frequently used in casual conversation to speculate about why someone is acting nervous or defensive.
Examples
He is being so evasive, he must have something to hide.
If you haven't done anything wrong, why are you afraid of having a guilty conscience?
