This homage to the Beach Boys alludes to their "perfect four-part harmonies" and cranking up the radio for inspiration. However the song was written by Rivers Cuomo intentionally to sound as little as possible like the titular surf rock icons.
According to Rivers Cuomo, the song describes his experiences of "being in downtown LA at night and being totally disoriented and alienated, and reminiscing about west side life in the early '90s and listening to The Beach Boys." (Source: Weezerpedia.)
The song concludes with some quotes from Murry Wilson, the abusive father of The Beach Boys' Brian, Carl and Dennis Wilson and one-time manager of the group.
