My children were outside playing and I was visiting with a neighbor.  All of a sudden my sweet little five year old son shouted "Sh..t, sh..t, sh..t!"  To say I was completely surprised was an understatement!  We didn't use that kind of language.  My neighbor was laughing and then I realized why...she was wearing a t-shirt with those words printed prominently across the front.  (I don't know why I didn't even notice it before).  Needless to say, I had a gentle little talk with my son about how, even if you CAN read certain words, they might not be good words to say.  Check with Mom if you don't know what a word means. 

Over the years, I've had many a discussion with my kids over some of these very commonplace (and completely unacceptable) words.  Because many of these words have to do with the functions of the human body, we'd have what we called Bathroom Discussions..which consisted of very matter-of-fact and clinical definitions.  Funny how certain words lose their appeal when you explain in detail their actual meaning.  Most of the time my kids would just say "ewwwww" and that would be the end of it. 

Your kids are going to hear (and see) all kinds of words at school, with their friends, on TV, and on T-shirts :)  You can't protect them from what goes on in the outside world, but you can teach them at home what is expected as members of your family.   Good luck!
