I find cursing most helpful to blow off steam in stressful situations.

Other times, it helps you be expressive. "Idiot!" doesn't quite say it as well as "F***ing idiot!"

Apart from that, it's pretty much gratuitous cursing, which I try to keep to a minimum.

I personally don't find anything wrong with swear words. I just try not to expose people who care not to be exposed or shouldn't be exposed, like young kids. In my family, the definition of a curse word is "something you don't say in front of grandmother."
