The song, written primarily by bassist and vocalist Mark Hoppus, lyrically revolves around the onset of age and maturity, and the failure to implement changes in behavior.
It was the first Blink-182 single to feature drummer Travis Barker.
It became Blink-182's second hit single, peaking at number two on Billboard's Modern Rock Tracks chart for ten weeks.
It was originally titled "Peter Pan Complex", an allusion to the pop-psychology concept, but MCA Records forced the band to re-title the song, as the label found it too obscure a reference.
Primarily an airplay hit, the song was the band's first to cross over to pop radio, hitting number 58 on the Billboard Hot 100.
