クソ

• 発音: /kɯ.so/

意味

Crappy, damn, or shit — a vulgar intensifier and all-purpose expression of contempt or frustration.

クソ literally means 'shit' but functions as a versatile prefix intensifier (クソ暑い = damn hot, クソゲー = crappy game) and standalone exclamation. As a prefix it amplifies the negative quality of whatever follows. While undeniably vulgar, it is extremely common in casual speech, gaming culture, and online discourse. Its shock value has diminished through overuse, though it remains inappropriate in polite company.

例文

1. クソ暑いのにエアコン壊れた、最悪。
2. クソみたいな映画に2時間も使って後悔してる。
3. クソどうでもいいことで怒るなよ。
