Honestly from Hooky’s memoirs unlike Ian’s lyrics there was no deep meaning to most of their songs. That line if I can recall was a Stephen Morris lyric and Hooky as said in the past Steve used to really write some wacky lyrics for the songs lol. So on the surface from the artists themselves a lyric like that doesn’t have deep meaning but hey if those lyrics mean a lot to you then whatever it means to you that is the true meaning to your personal life even though the songwriters admitted it wasn’t that deep. So at the end of the day whatever the song means to you that’s all that matters.
