[Verse 1]
Now I can drink, but I just don't care
I've been doin' it for years
I can do it anywhere

[Pre-Chorus]
And I still don't think I should have to brush my hair
My nails aren't pink and I like the way you stare

[Chorus]
I got a teenage heart
I got a teenage heart, yeah
I got a teenage heart and I just don't care
No, I just don't care

[Verse 2]
And my heart still jumps when they check my ID
And it's just so no fun when the picture's really meh

[Pre-Chorus]
Say I'm all grown, I should learn to sit still
But I don't give a fuck, I don't think i'll ever will

[Chorus]
I got a teenage heart
I got a teenage heart, yeah
I got a teenage heart and I just don't care (Teenage heart)
No, I just don't care
[Bridge]
I don't wanna behave, it's no fun
Sing, da da da da da da
Why should be a bore at 21?
Sing, da da da da da da
Do you really come out just to focus on the surface?
Sing, da da da da da da
Because I came to get down and I came to cause a ruckus
Sing, da da da da da da (Whoa)

[Pre-Chorus]
Say I'm all grown, I should learn to sit still
But I don't give a fuck, I don't think I'll ever will

[Chorus]
I got a teenage heart
I got a teenage heart, yeah
I got a teenage heart and I just don't care (Teenage heart)
No, I just don't, I just don't care care
No, I just don't, I just don't care
(Teenage heart)
No, I just don't, I just don't care care
(Teenage heart)
I just don't care care
Teenage heart, yeah
