also: ぼっしゅみ
noun, na-adjective
tastelessness; lack of taste; vulgarity
Formal or literary term describing a person, behavior, or thing that lacks refinement or aesthetic sense. Often used in critical or disapproving contexts.
彼の服装は没趣味だと言われている。
His clothes are said to be tasteless.
あの派手な装飾はまったく没趣味

Compound of 没 (ぼつ, 'without, lacking') and 趣味 (しゅみ, 'taste, refinement'). The geminated reading ぼっしゅみ arises from natural assimilation in speech.
