Cover art for Popular Monster lyrics by Falling In Reverse

As for the songs meaning the narrator is going through some type of mental issues. He describes such as being akin to “depression”. However, the people he deals with, i.e. “everybody” and his “doctor”, tell him that he’s just “going through a phase”. But as revealed later, this more like an existential crisis. But either way, the true purpose of this song is supposed to be how external pressures are negatively affecting him. And these factors do indeed transform him into the “popular monster”. And by “popular monster”, we can say he has become an unfavorable individual who was made so due to people perceiving him as such in the first place. So we can safely say the narrator’s internal issues coupled with external pressures have forced him to fully embrace his dark side.

My Interpretation

@EternalTearsOfSorrow So basically, he go crazy, become werewolf (YouTube Video), is popular monster, kills people, in trouble.
