noun, na-adjective
desperation; self-abandonment; recklessness out of despair
A state of not caring what happens because of despair or frustration; more emphatic than やけ. Often used in phrases like やけくそになる or やけくそで.
See also: やけ
試験に落ちて、やけくそで全部捨ててしまった。
After failing the exam, in desperation I threw everything away.
やけくそになってもいいことないよ。
Nothing good comes from giving in to despair.
Rare kanji form; literally 'burning dung'.
やけ means 'desperation' or 'recklessness from despair', but やけくそ is a stronger, more emphatic version often used in casual speech.
The exact derivation is uncertain. It likely combines やけ (desperation) with くそ (excrement) as an intensifier, similar to other vulgar emphatic compounds in Japanese.
