(ちゅうにびょう)

ちゅうにびょう
noun
adolescent delusions of grandeur
1. adolescent delusions of grandeur, chuunibyou syndrome
A colloquial term for the tendency of early teenagers (around second year of middle school, age 13-14) to act as if they have special powers, secret knowledge, or a dark and mysterious persona. Used humorously and self-deprecatingly.
あの()中二病(ちゅうにびょう)だ。
That kid has chuunibyou syndrome.
中学生(ちゅうがくせい)(ころ)中二病(ちゅうにびょう)をこじらせていた。
When I was in middle school, I had a bad case of chuunibyou.
(くろ)(ふく)ばかり()て「(やみ)(ちから)」とか()ってたのは、まさに中二病(ちゅうにびょう)だった。
Always wearing black and talking about 'the power of darkness' — that was peak chuunibyou.

中二病(ちゅうにびょう) literally means "second-year-of-middle-school disease." It was coined by radio personality 伊集院光(いじゅういんひかる) in the late 1990s.

Typical symptoms include:

  • Pretending to have supernatural powers or a hidden identity
  • Adopting a dark, edgy persona
  • Using grandiose or foreign-sounding phrases
  • Rejecting mainstream things as "for ordinary people"

COMMON COLLOCATIONS:

  • 中二病(ちゅうにびょう)をこじらせる (have a severe case of chuunibyou)
  • 中二病(ちゅうにびょう)全開(ぜんかい) (full-on chuunibyou)
  • 黒歴史(くろれきし) (dark history — embarrassing past behavior, often related to chuunibyou)

The term has become widely known through anime and internet culture, and most adults look back on their own 中二病(ちゅうにびょう) phase with embarrassment.
