boorishness

This term describes a specific brand of rudeness characterized by a lack of sophistication or social polish. It suggests a clumsy, uncultured approach to interaction that often borders on the offensive, evoking the image of someone who is oblivious to the expectations of polite society.

Because it refers to an abstract quality of behavior, this noun is uncountable. It cannot be pluralized or counted with numbers; instead, it requires partitive constructions such as a streak of boorishness or an instance of boorishness to describe specific occurrences.
