馬鹿野郎

baka-yarō

BAH-kah yah-ROH · /baka jaɾoː/

You stupid bastard / you goddamn idiot

3/5 Watch your audience

genuinely rude; friends only, never at work

Literally

"idiot bastard"

Word-for-word — which is rarely what it means.

How to use it

Baka plus yarō (a rough word for "guy/bastard") — a real, spat insult, not the playful baka. This is shouting-at-a-driver, coach-benching-you territory. Heavily male. Famous as the last radio words of a WWII-era diplomat, so older Japanese hear real weight in it. The kuso-yarō variant swaps in "shit" for extra venom.

Heard in the wild

何やってんだ、この馬鹿野郎!

What the hell are you doing, you idiot!

Where it lands

Nationwide; male-coded, confrontational
