noun
womanizer; philanderer; playboy
A somewhat rough, colloquial term for a man who habitually seduces women. Often carries a negative or vulgar nuance.
彼は女喰いで有名だ。
He is notorious as a womanizer.
あの男はただの女喰いだよ。
That guy is just a playboy.
Compound of 女 (woman) and 喰い (eating, from 食う), literally 'woman-eating'. The exact origin is uncertain, but it likely arose as a slang metaphor for consuming or devouring women.
