Bold and confident in a way that's rude or shows a lack of respect; impulsive and aggressive.
Origin uncertain, possibly from Old English 'bresc' (brittle) or related to 'brass' (the bold metal). By the 1500s it was used to describe people who acted boldly without proper respect. The metallic connection is likely—brass is hard and showy.
Brass instruments and brass personalities both got their names from brass metal—both are loud, showy, and hard to ignore! Medieval people saw brass as an inferior metal compared to gold or silver, so calling someone 'brash' was basically saying they were cheap and loud.
Applied asymmetrically: men described as 'confident' or 'bold'; women as 'brash' or 'aggressive' for identical behavior. Encodes gendered double standard in tone policing.
Use consistently across genders when describing behavior. Check: would this word apply equally if speaker were different gender?
