How about one more you fool? （ぼけなす）

He Says:
bokenasu　（ぼけなす）=idiot
Boke is fool, nasu is egg plant.
Especially used in Osaka. So they would be insult as fool and egg plant which is hard to understand...it's like a double punch.

She Says:
"You are one stupid eggplant."
"Back off, foolish eggplant!"
"Shut the fuck up you dumb eggplant!"
I think this is a word that definitely loses something in translation. I'm not convinced that any foreigner could pull this one off with the type of intensity needed to properly throw this insult. I mean, you could say it all angry-like...but then wouldn't you start to giggle when you thought about what it meant?

The next word is...へんたい。
