This triumphant, upbeat anthem deals with the aftermath of a break-up.
The title, Octo, is a reference to the lyrics from the 2nd verse:
"Yeah, baby, I'm the 8th Wold Wonder, the 8th continent,
The 8th deadly sin and day of the g*d-damn week,
The 8th Harry Potter book and the 8th big wide blue ocean,
Yeah, in a world of 7, I'm the greatest 8 you never thought you'd see."
