Which term refers to an act displaying a complete disregard for proper conduct?

The term that refers to an act displaying a complete disregard for proper conduct is "outrageous act." This term specifically implies an action that is shockingly bad or morally unacceptable, highlighting a blatant violation of societal norms and expectations. Outrageous acts are characterized by their extreme nature, often causing a strong negative reaction from others due to their disregard for acceptable behavior.

In contrast, the other terms do not capture the same level of disregard for proper conduct. "Irregular act" typically refers to actions that deviate from the norm but do not necessarily carry the same weight of moral outrage. A "negligent act" involves a failure to take proper care, which indicates a lack of intent rather than an outright disregard for conduct. "Reflexive act" describes actions that occur automatically or instinctively, without conscious thought, and do not align with the concept of intentional misconduct or disregard for propriety. Thus, the notion of an "outrageous act" distinctly encapsulates the idea of willful disregard for acceptable behavior.
