Lyric discussion by Warholkolic 

This is either Manson's confession or his exposee on the Hollywood child trafficking (see Pizzagate and Adrenochrome in Hollywood). The celebrity religion of Saturn ("my god"), invited to eat the young, the bottomless celebrity scar...

To me, it seems like Manson is/was in a relationship or good friendship with someone, and there was a discrepancy in the relationship about the morality of ingesting child-sourced adrenochrome, for which I think 'sunsets' in this song is a codeword, and the hard metal is the needle. It sounds like one of them is scarred by the practice (terror in the teardrop), and possibly that they need other drugs to cope with the reality ("make it snow"). "No matter how cold you are" either means the person is the evil one, or they have gone cold in the relationship after finding out the truth. The 'smile like a rifle' probably means they try to cope/pretend with a smile, but there is the very real threat of them 'triggering' to do something, like go out and tell people the truth. "Cast out now, no fire to smell" probably means a person has been banned from the Saturn religion, and can no longer be a part of the cultish practices.

The rest of the song seems to talk about the world ending or changing drastically, which has links with this elite circle.

@Warholkolic Adding to this, I think 'I don't wanna be another bullet hole In the exit sign on your road' means he doesn't want to be one of the people kicking the friend/lover out, because they probably have to kill them to keep the secret. The exit sign on their road is death -- where they get off the 'high way'. Him being another bullet hole is working with the others to kill the friend/lover, and he doesn't want to do it but he knows he must to protect their inner circle.
