brazen

This term carries a strong negative charge when describing behavior, suggesting a defiant lack of modesty or guilt. It describes a specific type of boldness that is offensive because it ignores social norms or moral boundaries, often leaving the observer stunned by the perpetrator's lack of remorse.

In its literal sense, the word refers to the material composition of an object. While this usage is less common in modern daily speech, it persists in historical, architectural, or biblical contexts to describe items crafted from brass, evoking a sense of rigidity and metallic luster.
