How it's used
This idiom carries a strong negative connotation, describing someone who is arrogant and dismissive of others. It implies a stubborn refusal to consider alternative perspectives, often leading to conflict in social or professional settings. Unlike simply being confident, this term highlights a lack of self-awareness and a tendency to act as if one is always correct.
Examples
He is always so opinionated and never listens to anyone.
Don't be so self-righteous, try listening to other people's opinions.
