[Intro – distorted guitar riff + drums kick in]
Yeah…
Na-na-na-na-na, oh, grow up.
---
[Verse 1]
Late-night texts, just “U up?”
Like I forgot all your messed-up stuff
You flake, you lie, you run, you hide
Then smile like everything’s fine
You want a gold star for bare minimum
But I’m not your prize or your kingdom come
Still blaming everyone but you
Tell me, do you ever follow through?
---
[Pre-Chorus]
You call it “chill” — I call it lame
Still playing those high school games
I moved on, you stayed behind
Good luck catching up this time
---
[Chorus]
You’re so immature (immature!)
Throwing fits like a boy on the floor
Say you care, but what for?
You're allergic to accountability and more
So insecure
I broke free, you slammed the door
Now you're just noise I ignore
Yeah, you’re so immature
---
[Verse 2]
Tried to talk, you rolled your eyes
Guess feelings make you petrified
Can’t say “I’m wrong,” can’t take the heat
But love ain't built on trick-or-treat
And now you're mad I'm calling it out
But baby, that's what real love's about
You want a fan, I want a man
Sorry if that wasn’t the plan
---
[Pre-Chorus]
Still think ghosting makes you cool
But honey, that's just coward fuel
I’m not your punchline, not your phase
You're just a page I’ve thrown away
---
[Chorus]
You’re so immature (immature!)
Always playin’ like love's a chore
Say you're deep — I need more
Than memes and ego battles galore
So unsure
Of who you are, what you stand for
You’re a game, not worth the score
Yeah, you’re so immature
---
[Bridge – breakdown, half-time drums, raw vocals]
Grow up, grow up, it’s getting sad
You want love, but can’t give it back
I gave you chance after chance
But you were busy… being a man-child
---
[Final Chorus – full band, loud & unleashed]
You’re so immature (yeah, you are!)
Throwing fits like you’re stuck at four
I’m not your mirror, not your cure
I’m done keeping score
So insecure
Keep your pride, your metaphor
I’m over it, and I’m out the door
You’re so immature
---
[Outro – fading guitar squeals + vocal echo]
Yeah…
Grow up.
