カオス

• 読み: カオス
• ローマ字: kaosu
• 漢字の分解: From English 'chaos' — borrowed as-is into Japanese with a lighter, more amused connotation
• 発音: /ka.o.su/

意味

Chaos — used to describe a situation that is completely disordered, unpredictable, or absurdly chaotic.

Borrowed from English 'chaos,' カオス is used as both a noun and a quasi-adjective (カオスな) to describe situations that have spiralled out of control in an often amusing way. Unlike the English word which can feel heavy or serious, the Japanese usage tends to be lighter and more entertained — describing a wild party, a bizarre conversation, or a situation where everything has gone hilariously wrong.

例文

1. 忘年会がカオスすぎて記憶がない。
2. タイムラインがカオスなんだけど何が起きた？
3. あの番組の展開カオスで好き。
