shamelessness

This term carries a strong negative connotation, describing a brazen disregard for social norms, ethics, or personal dignity. It suggests a psychological state where the internal mechanism of guilt or embarrassment has failed or been ignored, often resulting in behavior that is perceived as arrogant or offensive by observers.

Because it describes an abstract quality or state of being, the word is used as an uncountable noun. It does not have a plural form and is typically modified by adjectives such as "utter," "absolute," or "staggering" to emphasize the degree of the lack of propriety.
