crass

This term describes a specific type of insensitivity that is not just accidental, but strikingly blunt or devoid of any social grace. It carries a strong negative connotation, suggesting a lack of intellectual or emotional depth that makes the behavior offensive to others. While "tactless" might imply a simple mistake in judgment, "crass" suggests a more profound ignorance or a disregard for the dignity of a situation.

In modern usage, the word is frequently paired with concepts of money and materialism. When describing "crass commercialism" or "crass wealth," it refers to a vulgar display of riches that lacks taste or sophistication, emphasizing the gap between raw financial power and cultural refinement.
