Rikaichan browser dictionary has it as...
べらんめえ
(exp) bloody fool!

I've not heard of the ひ into し before.

I know lots of words are changed by men of all ages for example;
暑い - あっちいな
さむい - さみーな
高い - たけぇー！
わからない - わかんねぇぇ
なんとかじゃない　- なんとかじゃねぇし
I could go on for pages but in short, I asked my girl friend about べらんめえ and she went of about the Edo period and how it's not called that.

Interesting topic though.
