Personally i rarely use words for that nature and i never really have, when i am frustrated with something, then i might, or when i am annoyed. I tend to use these types of words much more when i have been drinking.

I beleive the kids of today swear (alot more then alot of us would have done), because that seems to be the way the english language is involving. (shortening words where ever possible, tendancy to use similar/shorter words), but alot of words especially the "F-word" are used more as a descriptive then it used to, but the biggest reason (or at least i think), when they say these words, nothing happens so they assume it's ok to say these words and eventually the don't even reliease (unless they are insulting someone) they are saying them.

Unfortunately, in 10-20 years this will be how nearly everyone speaks.

I don't mind it all that much (depending on situation and frequency), but it isn't nice to hear it especailly from young kids and i don't like it when people use them all the time
