I used to think that "damn" was a really bad swear word, but it was in one of my favorite songs at the time, "The Search is Over" by Survivor. I was shocked but rather excited by the badness of this, and I used to play it really loud and sing along in front of my mother, just to see what kind of reaction it would get out of her. She didn't notice at all. I wasn't sure if I felt triumphantly naughty or just disappointed.
