I want to share with you, in her own words, what Michaelson had to say about the meaning of the song and video because it's just so great (bold emphasis mine):
"Girls Chase Boys started out as a break up song but took on a deeper meaning as I continued writing. More than just being about my experience, its focus shifted to include the idea that, no matter who or how we love, we are all the same.
"The video takes that idea one step further and attempts to turn stereotypical gender roles on their head. Girls don't exclusively chase boys. We all know this. We all chase each other and in the end we are all chasing after the same thing: love. I hope you enjoy it! AHHH!"
