"Sk8er Boi" (pronounced "skater boy") is a song by Canadian singer-songwriter Avril Lavigne, released as the second single from her debut album, Let Go (2002). It was written by Lavigne and the Matrix (Scott Spock, Lauren Christy, and Graham Edwards), and produced by the Matrix. The song combines punk rock, pop-punk, power pop, and alternative pop styles, which lyrically tells a story told from the singer's viewpoint about her rocker boyfriend and a girl he knew in high school who rejected him because he was a skateboarder and she was a snob.
