The world expert on swearing, at least from psychological science, is this guy named Timothy J. He spent a good portion of his long career studying the upside, the downside, the mechanism, swearing in all possible facets. So I'm going to make the case for the upside is swearing, but I'm also going to say that net, I think it's unnecessary roughness. And actually, I have to say, I learned a lot about the science of swearing.
