What kind of "curse" words would you hear in Utah Valley when I was growing up? Well, there was "shoot", "darn", "fetch", "heck", and "jeeze" to name a few. One of the more common exclamations was "Oh my heck, no way!" However, it was so common, and often said very quickly, it was jokingly referred to as one word, hence, "ohmyhecknoway!"
There were those that told me that saying a substitute for a word was just as bad as saying the "real" swear word. For example, if I were to hit my thumb with a hammer and then proceeded to yell, "FETCH!" it was the same as dropping the F-bomb (that's a nice way we referred to that other "F" word).
On this point, I'm going to respectfully disagree. I don't believe that using a different word in place of a swear word is the same. Why? Simple. Words have power.
Now, I'm not talking about the "My name is a killing word" (Dune reference) type of power. I'm saying that certain words in and of themselves have power. For example: "I now pronounce you man and wife" has a totally different meaning than "I now pronounce you man and banana."
Need another example? How about instead of "You are under arrest" you say, "You are under a mattress". Still not convinced? All right, one more: instead of "You're fired!" you say "You're hired!"
