"Oxford Comma" playfully addresses the idea of caring too much about trivial rules. The song's title comes from a specific punctuation mark, which the songwriter first encountered through a Facebook group. While the lyrics open with a provocative question about the Oxford comma, the song is ultimately about the liberating feeling of not obsessing over minor details. It also features fun references to rapper Lil Jon, who even sent the band a gift in appreciation. At its core, it's a song that invites you to embrace a more carefree attitude.
