死亡フラグ

• Reading: しぼうフラグ
• Romaji: shibou furagu
• Kanji breakdown: 死亡 (death/dying) + フラグ (flag) → an omen that foreshadows doom or bad outcomes
• Pronunciation: /ɕi.bo.u.ɸu.ɾa.gu/

Meaning

Death flag — an omen or statement that foreshadows something bad happening, from anime and gaming tropes.

The most famous type of フラグ, 死亡フラグ originally referred to the trope in anime, games, and movies where a character says something that virtually guarantees their death — like 'when this war is over, I'm going home to marry my sweetheart.' In everyday slang, it has broadened to mean any ominous statement or action that seems to guarantee a bad outcome, even in trivial situations.

Examples

1. 「俺が絶対守るから」って死亡フラグじゃん。 I'll protect you no matter what' — that's totally a death flag.
2. 死亡フラグ立ちまくりで見てられない。 Death flags are going up left and right, I can't even watch.
3. テスト前に「余裕でしょ」は死亡フラグだって。 Saying 'this test is gonna be easy' before an exam is a death flag, I'm telling you.
