Cover art for Bulletproof Heart lyrics by My Chemical Romance

There is the obvious tie in to the rest of the album, but if you take this song by itself, I think it talks about being true to yourself and loving yourself for who you are. I think “bulletproof heart” means that if you love yourself then no one else can tear you down and destroy you. People or society can try to hurt you with words and what not, but your heart and feelings are bulletproof. If your true to yourself, god will save you. I think Johnny understands this and is trying to help Jenny. He is trying to help Jenny to stop caring about how society wants her to act or how certain people in her life want her to act and just be herself. I think that can mean different things to different people and why I feel this is an amazing song!!

@redhawk87 also, the line “I got a bulletproof heart, you got a hollow point smile” talks about how fake people can be. If your true to yourself and act like yourself, you won’t be fake. Your smile won’t be genuine. He would rather have a bulletproof heart than to pretend to be happy. He says “I’m who I got to be”. Meaning he is what he is and that is good enough for him and that’s all that matters. Again be true to yourself and love yourself and don’t try to be someone else.
