Manson has said that the murder "almost made me laugh, but it made me mad. When you think about it, it's so fucking backwards, despite the whole Christian belief of and all that." When writing the track, Manson also drew inspiration from his longtime fascination with abortion as well as an elderly man he saw at an anti-abortion protest. Manson remembered: "I had this thing that I bought at a magic shop in Florida that shot cotton-wad fire things out of the palm of your hand, and I drove up to him one day and said the devil's got a message for you and I shot the fireball at him and he ran." Commenting on both "Get Your Gunn" and "Lunchbox", Manson noted that "The somewhat positive messages of these songs are usually the ones that sensationalists misinterpret as promoting the very things I am decrying."
