This is a song about "Grind out"

"you out ya mind," nah, you don't know what's in my mind

I impress your mind, then i confess my grind

Baby, you don’t have to try to read my mind

Woke up this morning fully clothed ready to grind

Locked down in tha penitentiaryfinally lose my mind

Why does every rapper say you have to hustle and grind

Everytime i rhyme my mind is on the grind

In the gutter, you learn to have a criminal mind

An allusion to the grind

To my unborn child

You're my river runnin' high, run deep, run wild

Hatin on me cause i been on my grind/

Cause i’m back on my grind

As: they will be so surprised
