Avril Lavigne - Sk8er Boi (Official Video)

"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 alt-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 did ballet.

The song was well-received by critics, with most commending its hook, calling the song "funny" and "clever". It also received a Grammy nomination for Best Female Rock Vocal Performance at the 2003 edition. Commercially, "Sk8er Boi" was a success, reaching the top 10 in more than ten countries, such as Australia, New Zealand, the United Kingdom and the United States (becoming Lavigne's second top 10 single on the Billboard Hot 100 chart) and sold over 1.8 million copies worldwide. According to Spin, "Sk8er Boi" has the fifth best pop-punk chorus of the 21st century.

The music video for the song, directed by Francis Lawrence, features a concert on a city street with Lavigne singing on the hood of a car with a crowd rocking out around her. It was a success on Total Request Live and was voted one of the best music videos of the decade by BT TV. The song has been performed in all of Lavigne's concert tours to date.
