This is a song about "Mean girld"

New rolls royce, royce, yeah i'm all that

And i mean it (and i mean it)

Girl cut up, got lean on lean

Yeah fuck you he was so mean

And i mean it (and i mean it)

Double m-g not to mention we got that

I didn't mean to hurt anyone

All the girls really want is fun

He dont want the diamonds

You ll catch some mean lumps

Maybe cuz her dad used to be mean

I get paper like i a mail box, seen

Maintaining my modest modest as i dream

But im just playin, was that even mean?

My chick riding shotgun, billie jean

Whats non compos mentis mean?
