In an interview with musicomh.com
Kate Nash was asked if this song about the impending end of a relationship was based on personal experience. She replied: "I've never really had a long term boyfriend but I did have a relationship with someone and it was quite intense... and it got nasty and confusing, saturated and concentrated. Which one do I mean? They're opposites, aren't they? Sometimes it's just not the right person. As you go through life, hopefully, one relationship will click. Sometimes you go through ones that don't work, but you want them to work because you're attached to that person. You love them, but you might not like them anymore. And they might love you but might not like you. And you try to stay together. And you end up being really nasty to each other, and stabbing each other, and not knowing when it started or when it ended, and it being really confusing. I've seen it happen to my friends."
