It’s about me and my ex-boyfriend, and our tumultuous, psychotic relationship. We’d act weird, like drug addicts with each other, calling and seeing each other all the time. I was in love at the time, and (the song) sounds pretty happy, but it’s a little bit of a dark song. You’re so obsessed with somebody you start acting like a weirdo. … I write about falling in love, being in love, breaking up because he’s a loser, being heartbroken. I not only sing about getting rowdy, but love.

I wrote this song on an airplane in, like, 10 minutes and finished it with my mom. So it’s one of my favorites. It’s stupid and fun. You can’t take it too seriously. And so, the video, I wanted it to be like a psychedelic trip of the mind, comparable with being so disgustingly in love with someone that you lose your head. So I ride an elephant — no big deal! — and, um, I dance around a cave with black-light body paint and a python. I was in a cave, in the desert, and it was really fun. This video was inspired by the Beatles' ‘Yellow Submarine’ movie, the animation aspect. There’s a little bit of [that] in there too."
