[Verse]
I guess 3am on a 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 a feelin' you get, there's always a cause for it

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

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