scabrous

The term carries a dual nature, shifting from a literal physical description to a sharp moral judgment. In its physical sense, it describes textures that are abrasive or scaly, often evoking a sense of dryness or irritation. It is frequently used in biological or geological contexts to describe surfaces that are not smooth.

When applied to behavior or content, the word takes on a caustic, derogatory tone. It describes material that is not merely provocative but actively offensive or salacious. In this register, it is far more severe than "risqué" and suggests a lack of taste or a deliberate attempt to shock through indecency.
