High Noon: Minced 4-Letter Words

The other day something happened, can’t remember what, but I said, “Oh crap.”  “Mom,” my 8-year old son said, “you’re not supposed to say that.”  Well, it was better than what I really wanted to say.  While attending a Christian boarding school, I knew that I would have to curb the language, no four letter words here.  But what I didn’t know was that I was also not allowed to say shoot, darn or oh my goodness.  These are minced oaths-words based on profanity, but changed to make them less profane.  Didn’t know that expression until I was told at school/ Lisa Paolino , Are We There Yet.

Question: Do you use four-letter words much? Or mince them into something more acceptable?
