• This upbeat track is Maggie Lindemann's follow-up to her breakthrough hit "Pretty Girl." she explained the song's meaning to Billboard:
  
  "It's about being with someone more physically than being with them emotionally. Then, you know, obviously it's not as fun as always being a little obsessed with themselves and you're not able to really connect with them on any other level than that. It's not putting down being obsessed with yourself, because in the end it's like, 'I'm obsessed with myself too.' Just kind of talking about that and not being able to connect."
• The song has the same title as Maggie Kindemann's beauty campaign with British make-up artist Pat McGrath. Billboard asked the singer which one came first. She replied:
  
  "My song came first, and then we collaborated with Pat and came out with 'So Obsessed.' It wasn't all thought of at once but then once the idea came up it would be really cool to release it with Spotify and release it with the single. We thought it would be a cool collaboration kind of idea."
• Maggie Lindemann explained the song's inspiration to Genius: "We've all been with someone that is pretty self-absorbed or only cares about themselves or is obsessed with themselves," she said. "It was just to call them out, and, it's not even necessarily in a bad way. At the end, I go, 'Obsessed with myself, too.'"
