I spend the first decade of my working life on a building site as a Joiner/Carpenter, so dropping the occasional "B" word was never too much of an eyebrow raiser. I still don't cuss very often, and like Rekless, find the F-bomb kinda stupid. The way it's commonly used just makes it meaningless.
Ironically, words like ass and damn aren't really classed as full-out swear words in Britain. Seeing parents running for cover covering their children's ears, when I was over in the States, was an interesting experience
