Other forms: brassily; brassier; brassiest
Someone who's brassy is bold and flashy — and maybe even a little rude. That brassy kid in class seems to get all the attention, while their quiet, shy classmates get overlooked.
Use the adjective brassy to mean bold and brash, or to describe something that looks like the metal brass (but not in a good way): "He tried to dye his hair strawberry blonde, but it came out brassy." When something sounds brassy, it resembles a trumpet or trombone, or another brass instrument. The "brazen" meaning comes from a comparison of brass to gold; in the 16th century, brassy meant "strident and artificial."
