I'm usually not a big fan of cursing.  I used to have quite a few bad words to say, but I've since cleaned up my act a bit.  Whenever I hear young people using bad language, I don't think it's too cool because it just shows that they can't think of something more intelligent to say.  But I feel different with old people.  Old people have been around for a while.  They're wise.  They're patient (sometimes).  So when they interject some obscenities in their everyday speech, I think it's pretty funny.  Not only because it's usually undeserved, but because of their attitude. 

I was in a meeting last week, and some woman (not too old ... probably in her late 40s) was talking about her job experience and just threw in a couple choice words to describe some of the bad parts of her job.  It was hilarious because she didn't care what anyone thought.  She didn't care if it was offensive or if it would give a bad impression of her; she didn't care if it affected her job.  She just said what she felt.  It's like she reached that point in her life where she said what that guy in American Beauty said:  "I'm just an ordinary guy with nothing to lose."  Bravo. 

Disclaimer:  I can't and don't advocate the usage of foul language.  Such behavior is immature (sort of) and inconsiderate (sometimes) and will be deleted from this website (see comments here and here).
