Verse 1

No, that's not a word, I'm aware of that, I made it up, it's what I do.

Did you know I make up words to rhyme with the name that belongs to you?

Pre Chorus

And we can hate each other to our hearts' content.

I know it's never pretty when past meets present.

But we have to be cordial and polite.

Be mature, let's not fight.

Chorus

What are we?

Two high school teens fighting over a guy?

What was that?

A little effort to make me think he's lying?

Just because you called me kiddo,

Doesn't mean I'm a kid, you know.

You guys are history, now let it go.

Don't you try to make me insecure.

Be mature.

Verse 2

No, I won't fall for your little insults, I'll end this cold war between us.

I'll be warm towards you, you can throw punches, but I'll let it all pass.

Pre Chorus

And we can hate each other to our hearts' content.

I know it's never pretty when past meets present.

But we have to be cordial and polite.

Be mature, let's not fight.

Chorus

What are we?

Two high school teens fighting over a guy?

What was that?

A little effort to make me think he's lying?

Just because you called me kiddo,

Doesn't mean I'm a kid, you know.

You guys are history, now let it go.

Don't you try to make me insecure.

Be mature.

Bridge

You know, he and I do talk.

My life is not your lego-blocks,

You can't break us up and shake up my faith in him,

And your chances of making me drop out of college are pretty slim.

Verse 3

And maybe I'm overanalyzing and it's all in my head, for that I'm sorry.

But you came across to me as vicious today, but I'll try again, don't worry.

Pre Chorus

And we can hate each other to our hearts' content.

I know it's never pretty when past meets present.

But we have to be cordial and polite.

Be mature, let's not fight.

Chorus

What are we?

Two high school teens fighting over a guy?

What was that?

A little effort to make me think he's lying?

Just because you called me kiddo,

Doesn't mean I'm a kid, you know.

You guys are history, now let it go.

Don't you try to make me insecure.

Be mature.

Be mature.

Be mature.
