Stylistically, the album has been categorized primarily as
punk rock, Additionally,
Loudwire stated that the album represented
scene music in the 2023s.
NME characterized the album's sound by "crashing drums, razor-wire guitars, [and] a double helping of
fuck you attitude", and Arielle Gordon of
Pitchfork stated that the album "made apathy sound apoplectic". Many of the album's tracks have brief runtimes; Fred Thomas of
AllMusic noted, "the way the tracks fly by nervously in barrages of buzzing guitars and half-sung, half-sneered vocals from Billie Joe Armstrong intentionally aims to obscure how precise their
arrangements are." Jason Chow of the
National Post characterized the tracks themselves as "furious but sweet melodies". Lyrically, the album is characterized by its "
irreverent attitude",
PopMatters summarized the album's theme as "a record that speaks of the frustrations, anxieties, and apathy of young people". The song revolves around a mentally ill character who plans to use explosives to kill himself and others. This was not regarded as a serious issue at the time, as the social climate could allow the song to be viewed as "mere cathartic fantasy", but later incidents such as the 1999
Columbine High School massacre have made the song the "most uncomfortable track" on the album. On "Chump", Armstrong takes the perspective of someone who shows prejudice, insulting another person without actually knowing them. At the end of the song, it is revealed that the disliked person in question matches Armstrong's description of himself. "Chump" is also the first of three songs that allude to Amanda, a former girlfriend of Armstrong's. In an interview with
Guitar World in 2002, Armstrong described the character in the song as based on himself when he lived in
Rodeo, California: "There was nothing to do there, and it was a real boring place." To entertain himself, the character does nothing but watch television, smoke
marijuana, and masturbate, and has little motivation to change these habits despite tiring of the same cycle of behaviors. "Pulling Teeth", one of the album's slower songs, uses dark humor about
domestic violence. The typical victim and perpetrator are reversed; the male narrator is at the mercy of his female partner. The band's inspiration for this song came from a pillow fight between Dirnt and his girlfriend that ended with the bassist breaking his elbow. The second single, "
Basket Case", which appeared on many singles charts worldwide, was also inspired by Armstrong's personal experiences. The song deals with Armstrong's panic attacks and feelings of "going crazy" before being diagnosed with a
panic disorder. In the second verse, "Basket Case" mentions soliciting a male prostitute; Armstrong said, "I wanted to challenge myself and whoever the listener might be. It's also looking at the world and saying, 'It's not as black and white as you think. This isn't your grandfather's prostitute – or maybe it was.'"
Songs 8–14 "
She" was written about Amanda, who showed him a feminist poem entitled "She". Amanda is also referenced in the next track, "Sassafras Roots". The tenth track, "
When I Come Around", was the album's final single. It was inspired by Adrienne Nesser, Armstrong's girlfriend and eventual wife. Following a dispute between the couple, Armstrong left Nesser to spend some time alone. The song "Coming Clean" deals with Armstrong's coming to terms with his
bisexuality as a teenager. At the time, he was still looking for himself sexually and had no well-defined sexual orientation. In his interview with
The Advocate magazine, he said that although he has never had a relationship with a man, his sexuality has been "something that comes up as a struggle in me". "Emenius Sleepus", written by Dirnt, is about two old friends who meet by chance, and the narrator realizes that they have both changed a lot as people. Played in a quick
staccato-styled rhythm, Armstrong wrote the song "In the End" about his mother and stepfather, and the reproach Armstrong felt toward his mother for choosing his stepfather as a partner. "F.O.D.", an acronym for "Fuck Off and Die", begins calmly with Armstrong alone on acoustic guitar, before the band suddenly arrives in a louder, full-force fashion. The theme of the song centers around the singer's grudge for another individual, and wishing misfortune upon them. A
hidden track, "All By Myself", with vocals and guitar by Cool, plays after "F.O.D." ends, and is about masturbation. ==Title and artwork==
