The thing I've learned over the years is, swearing is best used rarely, because then it has more oomph. When you see somebody swear constantly, you just tune it out as white noise. Swearing is like a good spice. A little goes a long way, and more than a little tends to drown out everything else.

Sometimes it just strikes me as lazy too. 'Dude, you're fucking stupid", that's just boring as insults go. I mean, c'mon, if you're going to go through the trouble of insulting someone, invest a little time in it and do it right. Like, "Dude, a boil on a diseased prostitute's oozing pus-rimmed anus has more brain cells than you do" or something like that. Hell, that didn't even contain ANY profanity.

It doesn't bother me, profanity. I can curse in three languages, and I was in that great bastion of profanity, the U.S. Army. But I save it, use it judiciously, so that when I do use it it's not just white noise.
