Lyric discussion by timothy116 

At first I thought it was about another girl that got away, but as I listen more carefully, it's about "a girl and her dad", as said in the lyrics. Then it all made sense.

So he's fighting for custody for his daughter (Maddie), and the other side of the family is trying to make Maddie forget about him. He's struggling with money, it could be one of the reasons of the breakup. He gives Maddie something to remember him by, but tells her to keep it a secret. He's confident that he'll get custody of Maddie as he fights FOR her, whereas the other side fights OVER her.

More in depth: I was just copying and pasting lyrics, then I realised that as with most Descendents songs, the lyrics are pretty self explanatory. Reads like a book.
