Cover art for Shake Shake lyrics by Tilly and the Wall

This song, to me (and I could be terribly wrong, but this is just my interpretation) is about a guy who's in love with a girl who sleeps around (example 1: "And its just motion/Yes everybody knows it", with motion referring to sex)(example 2: All this flesh you're touching/And still it don't mean a thing). He wants to be exclusive, but she doesn't think there's anything wrong with being with other people.
