The word 粗暴 is formed through the conceptual fusion of its two component characters. The first character, 粗, carries the core idea of coarseness, crudeness, and lack of refinement, much like rough-hewn material. The second character, 暴, injects the notions of suddenness, violence, and unrestrained intensity, akin to an erupting storm. By combining them, the term creates a compound meaning where inherent roughness (粗) is amplified and activated into aggressive, harsh, and unrestrained action (暴), resulting in a complete portrait of brutish behavior.
