Well, when I got hit by a car (as a driver, not as a pedestrian), I saw it coming. I slammed my fist on the dashboard and shouted at the top of my lungs, "Noooooo!" It's amazing, when I'm really mad or hurt I tend not to cuss. Cussing usually comes out more conversationally. I'm not particularly proud of that, it's just the way it is.

Things I do say (I do try not to cuss) are:

You son of a dog
You son-of-a-son-of-a
That just sucks out loud
What in the cat hair are you doing? (I stole that one from my sister.)
I can't believe you did that!
Jeez Louise (some may consider that too close to cursing – I don't.)
Not good.
and the ever popular, Oh oh.

Most of these are uttered sub vocally, or at other drivers who never get to hear my incredible creativity. ;-)

A lot of people tend to swallow there words, particularly at the end of a sentence or phrase. So you could just let the old ellipses do your talking for you:

What the...
You son of a ...
You stupid...

Dyalyn is right. Whatever you do just has to sound natural and in character. I realize that some people cannot bear to use curse words in their writing, and that is fine. But if your character is a hard core criminal who has spent time in prison for not being a very nice person it's not going to sound very convincing if he tells someone, "I'm going to kick your bottom."
