What is the term used to describe the behavior that should be prohibited as socially unacceptable?

The term "abhorrent" is used to describe behavior that is considered morally reprehensible or socially unacceptable. This strong word conveys a sense of disgust or loathing toward actions or behaviors that violate social norms or ethical standards. When something is labeled as abhorrent, it indicates a deep-seated rejection by society.

On the other hand, "flagrant" refers to actions that are conspicuously bad or offensive, but it does not necessarily carry the same moral weight of social unacceptability as "abhorrent." "Ineffable" describes something that is too great or extreme to be expressed in words, and it does not relate to socially unacceptable behavior. "Elucidate" means to make something clear or explain, which also does not connect to the idea of prohibiting socially unacceptable behavior.

Thus, "abhorrent" aptly captures the essence of behavior that society deems unacceptable.
