コミュ障

• Reading: コミュしょう
• Romaji: komyusho
• Kanji breakdown: コミュ (abbreviation of コミュニケーション, communication) + 障 (abbreviation of 障害, disorder) → communication disorder
• Pronunciation: /ko.mjɯ.ɕoː/

Meaning

Socially awkward — someone who is terrible at communication and struggles with basic social interactions.

A casual abbreviation that labels someone as having a 'communication disorder.' While the full term 障害 (disability) is clinical, the abbreviated slang version is used lightheartedly, especially in self-deprecation. Saying 「コミュ障だから」 (because I have komyusho) has become a common excuse for avoiding social situations. The term reflects Japanese society's emphasis on smooth social interaction (コミュニケーション能力 = communication ability), which is considered essential in both school and work.

Examples

1. 自分、コミュ障だから飲み会とか無理。 I'm so socially awkward that I can't handle drinking parties.
2. コミュ障すぎて初対面の人と話せない。 I'm so bad at socializing that I can't even talk to people I'm meeting for the first time.
3. コミュ障って自称する人、意外と普通に話せるよね。 People who call themselves socially awkward can actually hold a conversation pretty normally.
