意味

Raising a flag — saying or doing something that sets up a predictable outcome, essentially jinxing it.

To フラグ立てる is to unknowingly (or knowingly) set up a situation where the predictable opposite will happen. Classic examples include saying 'I definitely won't be late' (guaranteeing you will be) or 'this should be easy' (guaranteeing it won't). The phrase treats life like a scripted story where certain statements trigger inevitable outcomes. Often used as a playful warning: フラグ立てるなよ (don't raise a flag!).

例文
