無表情

• 読み: むひょうじょう
• ローマ字: muhyoujou
• 漢字の分解: 無 (without/none) + 表情 (facial expression) → completely devoid of any expression
• 発音: /mu.çjo.u.dʑo.u/

意味

Expressionless — a completely blank face showing zero emotion, used to describe an extreme deadpan reaction.

More intense than 真顔, 無表情 describes a face that shows absolutely no emotion whatsoever — not even the effort of trying to look serious. In slang usage, it describes the reaction of someone who is so unimpressed, bored, or done with a situation that their face has gone completely blank. Often used on social media to describe reactions to cringe content, boring meetings, or incomprehensible situations.

例文

1. 上司のスピーチ長すぎて全員無表情だった。
2. 無表情で「へー」って言うの怖すぎ。
3. バグ5回目で完全に無表情になってる自分がいた。

避ける言い方
