According to the band's website, this song is about a lovesick vampire.
Bass player Jared Followill explained how the band got the song's unique sound in State Magazine: "That was really quickly, off the cuff. We were sitting around the studio and as far as the bassline goes, I had a bassline that me and Nathan were working together on. But as we don't use a clicktrack, it was like a repeat pedal that we couldn't get down so we thought about not even doing it. Right before we started, I clicked on an octave pedal and started playing with, had some reverb on it. All the guys liked it and it's the thing that starts off the record which most people think is a keyboard. We came in and put a lot of reverb on everything, Matthew found out his pick-up on his guitar picked up his voice so a lot of those really atmospheric sounds, that's Matthew screaming into his guitar."
