• "Bobby Sox" starts off as a punchy love song as Green Day frontman Billie Joe Armstrong asks his object of affection if she wants to be his "girlfriend." But here's the twist: midway through, Armstrong throws a curveball, replacing "girlfriend" with "boyfriend" in some lines.
  
  "It's the '90s song that we never wrote," said Armstrong. "It started out being a song I wrote for my wife but as it materialized, I wanted to switch it up and added, 'Do you wanna be my boyfriend?' on top of 'Do you wanna be girlfriend'... So the song becomes a kind of universal anthem."
  
  It's a reminder that Green Day, even decades into their career, still knows how to surprise and celebrate our differences with a single, punchy stroke.
• Armstrong is bisexual, which he sang about on the Dookie track "Coming Clean." He stated in a 1995 interview with prominent LGBTQ+ publication, The Advocate, that "Coming Clean" is about coming to terms with himself as a teenager.
• Speaking to the LA Times, Armstrong recalled playing "Bobby Sox" to a friend about his same age. "It brought a tear to his eye when he heard the second verse," Armstrong said.
  
  "Nowadays it's more common for kids to be LGBTQ, and there's more support. But for us, back in the day," he added. "That was like the beginning of when people were able to openly say things like that."
• Bobby sox were knee-high socks worn by young women in the 1940s and '50s associated with teenagers and early rock and roll culture. They don't appear in the lyrics, so why the "Bobby Sox" title? Using the term instantly conjures up a nostalgic feeling of that time period, which reflects the song's overall vibe of a classic love song paired with the band's early '90s punk roots.
  
  Beyond fashion, "bobby sox" can symbolize youthful rebellion and carefree attitude, especially for women. This aligns with the song's questioning of societal expectations.
• "Bobby Sox" leans into Green Day's 1990s fuzzed-out punk sound. Producer Rob Cavallo incorporates chunky guitars and pounding drums in the mix, throwing longtime fans back to the band's Dookie era. (Cavallo also produced Dookie).
