The Vietnamese word "xấc" is an adjective that means "impolite" or "rude." It is used to describe someone who behaves in a disrespectful or inappropriate manner, often in social situations.
In a more advanced context, "xấc" can also imply a lack of decorum or propriety in formal settings. For instance, you might use it to describe someone who interrupts others or speaks loudly in a quiet environment.
While primarily meaning "impolite," "xấc" can also carry connotations of being cheeky or insolent, especially when someone is knowingly rude, perhaps as a form of defiance.
