So whatcha wanna do?
Let's just run girl.
If we wake up and you wanna break up that's cool.
No, I won't blame you;
It was fun girl.

And we'll go, go, go, go-go.
If you're ready, like I'm ready.

Cause it's a beautiful night,
We're looking for something dumb to do.

Cause it's a beautiful night,
We're looking for something dumb to do.

Is it the look in your eyes,
Or is it this dancing juice?
Who cares baby,
I think I wanna marry you.
