• The lyrics of this goofy thrash number present a 17-year-old girl who, "don't wanna go steady" because she's "probably not ready." The female in question is model, Amanda Norgaard, whom Vaccines lyricist and vocalist Justin Young has only met once. He told the NME: "She was beautiful but she kissed my friend. It didn't affect me as much as the song might suggest it did but I thought it would an interesting experiment to write a song about something that wasn't beating me up. I'd only ever written about things I was obsessing over, it made a nice change and came pretty easy."
• Nørgaard is a Danish model, and Young disclosed to Q magazine that he wrote the song after a disastrous double date with the Dane. "This other girl and my friend… who got off with the pair of them," he sighed. "I usually can only write when I'm agitated about something."
• This was released as the fifth single from What Did You Expect from the Vaccines? and Amanda Norgaard features in the song's music video.
