Cover art for Growing Up lyrics by Fall Out Boy

For once I think the title actually does explain it all: This song is about growing up!

The first line: I dried my eyes now I crust them with sleep. I'll crust them over. It's a little vague, but I think it's a line about maybe getting out of a relationship, drying your eyes of the tears shed over the last loss. Crusting my eyes over with sleep I think means ignoring the obvious issues in a relationship because your in a haze, like sleep. Crust them over completely because you can get pretty oblivious, almost blind!

The next part: She begged me "dont hate me". she spun me a story Where winning looks like losing and i'm winning every time. so thread spools sweetie, get ready. Until my silk is sold.

She begged me "don't hate me", "don't hate me" is a pretty grade school thing to say before you break up with someone kinda insinuating that it might have been a very early relationship, and that it had finally become obvious that the relationship was over. She spun him a story where winning looks like losing etc., is the typical break-up "oh it's not you, it's me" bullshit where you're clearly losing that relationship, but they want you to believe you're winning some sort of freedom. The last part is basicly saying, yeah, yeah I've heard it before just make it good and convincing.

The Chorus: Growing up, is just restating the obviousness of the theme I kinda disagree with what's written I think it says, I'll find myself a new, taking some downtime to just be single maybe?

I'm losing interest so I'll be quick the rest of the song is about another attempt at going out, there it ending negatively because he still had feelings for the last relationship and realizing he's better off on his own still, part of being a grown up and being in a relationship is knowing when to take some me time and that's what growing up

where eagles dare is a song about how your going miss me cuz I'm awesome, which kinda fits in to my explanation
