Wondergirl by Hey Monday is a song about a strong, independent woman who refuses to be the savior or rescuer for someone else. The lyrics suggest a one-sided relationship where the other person is relying heavily on her for support, but she's not willing to sacrifice her own well-being for that person. The song begins with the protagonist going at the speed of sound, implying that she's moving forward and away from someone who is stuck on the ground, calling out for help. She establishes that she's not going to be "your Wondergirl," indicating that she won't be the one to save the other person. The chorus repeats this sentiment, reinforcing the idea that she won't be dragged down by someone else's problems. She's not going to let herself burn in their flames because she won't save their life. The lyrics suggest that she's been through this before and won't repeat the same pattern of being a rescuer. The bridge implies that the relationship ended badly, and the protagonist couldn't keep up with the other person's addictions. The final chorus restates that she won't be the one to save him, even if he says he loves her. Overall, Wondergirl is a song about the importance of self-preservation and setting boundaries in relationships. It's a reminder that you can't save someone who doesn't want to be saved and that you need to look out for yourself before you can help others.
