See, I remember you when you were
The young new face, but you do like to slumber, don’t you
Now your boo up too, hon
I'm-a ruin you, cunt

She remembers you when you were coming up, but you’ve been sleepin on the grind. Now you’re fading, and she’s taking this opportunity to fuck your shit up.

If it’s at Nicki: “See, I remember when you were the new young face, but you like to slumber (sleep on me), don’t you? Now your boo up (making hits) too, hon. I’m-a about to ruin you cunt,” a.k.a. “I am about to fuck your career up when I drop an album.”
