How it's used
This idiom carries a strong sense of social ostracization and public contempt. It is typically used to describe someone whose reputation has been completely destroyed due to their own actions, rather than someone who is merely disliked by a small group. The imagery of a rat scurrying across a street evokes a visceral reaction, implying that the person is not just unpopular but actively avoided or despised by the general public.

Common mistake
Do not use this to describe someone who is simply unpopular or shy. It is reserved for individuals who have committed a social transgression or moral failure that makes them a target of collective hostility.
