Cover art for The Giant's Drink lyrics by Gatsbys American Dream

I think this song is more of a reference to Orson Scott Cards squeal to Enders Game, Enders Shadow, which deals with Bean.

"I will be the fire on your lips"

Bean knows from the start that hes smarter than everyone else, and that his abilities can help Ender achieve his goals

"But I'm overlooked and underfed"

It stated early on that Bean is extremely small for his age, and grew up starving and underfed in the streets of Rotterdam.

"I just see a little baby boy Who won't admit that he fucks up He's looking for the fire and the fury it takes to be a man But I just see a little baby boy"

More references to Bean being young, and also very cocky because he is very smart.

"I've got a secret And you've got a problem I'll disappear"

I believe this is a reference to Bean later in life, once he's found out that he is the only person like him, Super-smart but with a life-span of about only 20 or so years. This is his secret. "You've got a problem" may be referring to his wife (Petra) that he has to leave behind with his normal children, while he himself takes a star ship into space with his afflicted children, and they "disappear" from humanity.
