I'm not a guy who curses very much in my personal life. When I curse it sounds like a kid trying to be cool. But I think there are quite a few people, my father being one of them, who use curse words rather eloquently.
It's fun to be on the edge. I think you do your best work when you take chances, when you're not safe, when you're not in the middle of the road, at least for me, anyway.
