This is a song about "Cell wall"

I was at the xxl just trying to excel

And the only block he's reppin' is a h-block cell

Painting inextinguishable sentences on the wall

Come and stay with me, oh, where i live? the mall

She got a fat ass, she prolly know me well

These wack bars imprison me like i'm raised in a cell,

When my backs against the wall

Now we must stand tall

Been calmer than dahmer up in a prison cell

Keep it on the low, never kiss and tell

Tactical, my brains cell are individual

Don’t wanna have me then somebody will

These joints here not found at the mall

What's with the knife on the wall?
