badly mis-heard lyrics (mis-quoted perhaps?)
This happens to me all the time you guys, and I work in radio. I can honestly say I always mis-quote lyrics. My favorite thing to do is start singing along in front of people REALLY REALLY LOUD and all of a sudden they correct me and say those aren't the lyrics. (It happens a lot) Do you have any songs you can think of that you mis-quote? Maybe you don't even realize you're singing it wrong. That's what happens to me. I think I know the song and soon realize oops! that's not what I've been singing..
