Jay’s gift to his daughter, to stop using the word “bitch”.
Letter to Blue Ivy Carter from Jay Z :

Before I got in the game, made a change, and got rich,
I didn’t think hard about using the word B—-.
I rapped, I flipped it, I sold it, I lived it
now with my daughter in this world
I curse those that give it.
I never realized while on the fast track
that I’d give riddance to the word bitch, to leave her innocence in tact.
No man will degrade her, or call her out her name
the women won’t despise her and call her the same.
I know it’s gonna miss me
cuz we been together like Nike Airs and crisp tees
when we all used to hang out front
singing 99 problems but a lady ain’t one.
Excuse me miss, can I be your mister
cuz I can tell the difference from a little girl and a sister,
She never grew up, her father left her alone
I promise not to talk like we used to
until Kingdom Come.
I’m so focused on your future,
The degradation has passed
I wish you wealth, health, and insight
forever young you may pass.
Blue Ivy Carter, my angel.
