Does 'piss off' mean to urinate?

No. It is a crude expression meaning to anger. [ His attitude really ****** me off. ] It should not be used in polite conversation or in formal writing!

Thanks..

Can I say: "I was ****** off by his attitude"(The pasive voice)?

The passive voice is very commonly used. It means (something, somebody) made me very angry.
It is crude, but not as rude as some other expletives.

This is a very funny question

Okay..I got it...I thought it weird because "I got ****** off" this sentence I thought had a conotation of "Someone urinated on my face..."

CharmYouOkay..I got it...I thought it weird because "I got ****** off" this sentence I thought had a conotation of "Someone urinated on my face..."

That preposition would be on.

No, not at all. You will hear this sort of thing a lot:

My boyfriend really ****** me off yesterday when he asked my best friend out for a date. I'm still ******. If he does it again, he's history as far as I am concerned.

While we're on the subject, when an American says he's ******, it means he's angry. When a Brit says he's ******, it means he's drunk.

I hadn't thought of that meaning, which is also used by some in the US.
