Crap is NOT A CUSS WORD!
I DO NOT think CRAP is a cuss word! Because it's not. What's in a word anyways!
It doesn't really have a story behind it to make it a cuss word, it's just a word. like what if someone decided that they were gonna make the word ouch a cuss word. It's just a word, and so is crap there's nothing to it. It's that simple!
