[Verse 1]
I guess 3 a.m. on the guys' trip ain't what I thought it was
Falling in love with a boy's like death by ten thousand cuts
"I'm all you want" and, "She's not your type" means the opposite
And that's the feelin' you get, there's always a cause for it

[Pre-Chorus]
Mm, I put all my faith in you
I'm the one you can't afford to lose

[Chorus]
Grow up
If you want me, baby, baby, show up
Get your shit together if you know what's good
Every door got a spot to be shut
If you don't grow up, up, up, up, up
Grow up
If you want me, baby, baby, show up
I can't wait forever, wishin' that you would
Every door got a spot to be shut
If you don't grow up, up, up, up, up
(Up, up, up, up)
(Up, up, up, up)
