意味

Going crazy — used hyperbolically online for extreme excitement, shock, or frustration when something blows your mind.

Literally meaning 'onset of madness,' 発狂 is used in internet and gaming culture as a dramatic way to say you lost your composure. 発狂した means 'I went insane' or 'I lost it' — typically from excitement over an announcement, rage at a game, or shock at unexpected news. It is almost always hyperbolic rather than literal.

例文

  1. 推しの突然のライブ配信に発狂した。
  2. ラスボスに10回負けて発狂しそう。
  3. 合格通知が来て家族全員で発狂した。
