Songs that were popular that you didn’t initially realize were dirty?

I had been humming Chappell Roan’s Casual for a bit when one day I looked up the lyrics. And it reminded me of other songs over the years that I like/love that I did not initially realize were dirty or had dirty bits in them.

For example, as a kid, I walked around singing the “Doo doo doo” parts of Walk On The Wild Side by Lou Reed, long before I really caught on to some of the lyrics.

EDIT: since some people seem to think I’m a tad slow, the reason I did not realize Casual was dirty is that my wife played it for me while I was driving. Since I was focused on the traffic, I noticed that I liked the music and her voice. So, the music stuck with me and it kept creeping into my head and I finally looked up what she was singing about. 😊
