How it's used
This phrase is a strong personal attack that targets someone's upbringing rather than just their specific action. It implies that the person's parents or guardians failed to teach them basic social norms. Because it is highly offensive and confrontational, it is usually reserved for serious situations where someone has committed a significant breach of etiquette.
Examples
It is really rude of him to interrupt like that.
Why are you being so ill-mannered?
Common phrases
to call someone ill-mannered
to be scolded for having no manners
Common mistake
Avoid using this phrase in casual or lighthearted situations, as it is considered a severe insult to the person's family background. It is not a synonym for simply being naughty or mischievous.
