egregious

This term describes a mistake or action that is so glaringly bad it cannot be ignored. It carries a heavy tone of condemnation, often used in legal, professional, or formal contexts to highlight a failure that exceeds the bounds of ordinary negligence or error. While the word historically meant remarkably good, in modern English it is used exclusively in a negative sense. It suggests a level of shock or disbelief at the scale of the blunder, making it more intense than words like bad or incorrect.
