Don't mean jack

Why do you say you can't when you can
Tell me to suck it up and be a man
Why you gotta be so cruel to me?

And now you're acting like you won't move on
And trust me babe I'm trying to stay real strong
But now you're saying that you want me back
And it don't mean jack
It don't mean jack

Why would you wanna make a pretty girl cry?
You always told such awful lies
You tried to hurt my self esteem, you only hurt yourself.

And now you're acting like you won't move on
And trust me babe I'm trying to stay real strong
But now you're saying that you want me back
And it don't mean jack
It don't mean jack

Ohh wah oooh oooh
I don't need you oooh x4
It don't mean jack x5
It don't mean shit
