I freakin love this song! My friends showed me the video, and now I'm totally addicted to this song and I'm addicted to the video! I'm sooo addicted! I couldn't get the song outta my head all day and I actually was seeing little bits of the video all day in my head!
I think this song is saying that you should be yourself and not what people want you to be. I also kinda think that he's saying that if you don't like the way I am, go suck an egg.
