Which word describes something that is conspicuously and outrageously bad?

The word "egregious" is the term that specifically describes something that is conspicuously and outrageously bad. It originates from the Latin term “egregius,” which meant “standing out from the flock” and has evolved in modern usage to denote actions or behavior that are remarkably wrong or offensive. This aligns perfectly with the context of the question, as it emphasizes a significant deviation from the norm in a negative sense.

In contrast, "magnanimous" refers to someone who is generous or noble in spirit, especially in forgiving others, which does not relate to the idea of badness. "Benign" describes something that is gentle or harmless, which is the opposite of being bad. Lastly, "meticulous" refers to paying great attention to detail, suggesting carefulness rather than any negative connotation. These distinctions clarify why "egregious" is the appropriate choice for describing something notably bad.
