In an interview with NME, Fran Healy described the song as, "A tongue-in-cheek warning about the dangers of getting into a relationship with a girl who, despite looking much older, is actually under the legal age of consent. As the age of consent in Scotland is 16, Healy named the song "U16 Girls". The single's artwork depicts a surfboard which was designed by The Stone Roses guitarist John Squire. The surfboard is decorated with lyrics from Beach Boys songs. The single charted at number forty on the UK Singles Chart.
