boorish

This term describes a specific type of rudeness characterized by a lack of social grace or cultural refinement. It suggests a clumsy, unpolished nature rather than calculated malice, often evoking the image of someone who is oblivious to the social norms of a sophisticated environment. While similar to "rude," it carries a stronger connotation of being uncultured or peasant-like in behavior. It is typically used in critical or judgmental contexts to describe people who are insensitive to the feelings of others due to their own lack of sophistication.
