audacity
boldness / daring / impudence / nerve
Noun
This term carries a dual nature, oscillating between a positive trait of bravery and a negative trait of arrogance. When used positively, it describes a spirited boldness or a daring willingness to defy convention to achieve a goal. In most modern social contexts, however, it is used pejoratively to describe a shocking lack of respect. It suggests a boundary has been crossed, where confidence transforms into insolence or gall, often evoking a sense of disbelief in the speaker.
