In an interview with Songfacts, Romans stated about the origin of the song's title: "'Jenny' is just a name. A name that scans well in songs," adding: "A lot of people are like, 'Okay, who's Jenny?' It's more a representation of anyone being fickle."[2] There have been several rumors suggesting that the song is referencing a possible friendship between the band and South Korean singer Park Bom whose English name is Jenny due to them both attending the Berklee College of Music together. In 2016, the band's former lead vocalist Kyle Patrick said in response to the rumors circulating the song on Twitter: "We may never know the truth."[3]
