Background and release
Machine Gun Kelly described the upcoming album in terms of growth, stating to Variety, "I think like, in high school, you don't really have a sense of responsibility, you have a fear of that responsibility, and so you want to explode and use all that energy for fucking off. And then college comes, which is this album, and you are aware of the responsibility and you still know how to have fun, but you understand that there's a certain duty you have to your life to do something with it. Born with Horns feels like it has an objective or a real lesson that you're walking away with."

He and producer Travis Barker had tattooed the former name of the album, "Born with Horns," on their arms. In January 2022, Baker officially announced the change in title over a TikTok skit. The lead single, "Emo Girl", was released on February 3, 2022, that featured Willow Smith. Followed by this was the reveal of the album's release date.
