crass
UK: kræs | US: kræs
adj. lacking sensitivity, refinement, or intelligence; grossly vulgar or stupid
adj. coarse or crude in quality or appearance
The word "crass" originates from the Latin crassus, meaning "thick, dense, or solid." Over time, its meaning evolved metaphorically to describe behaviors or qualities that are "thick" in the sense of being unrefined, insensitive, or obtuse. The transition from physical thickness to figurative coarseness reflects a common linguistic pattern where tangible attributes are applied to abstract traits.
