This is a song about "Raincoat"

You have to have true penmanship to trespass onto my premises

Together we saw bodies in half to put on our walls as replicas

I'm not talking m3's, but this is your survival lease

Stackin' these rhapsodies that even queen couldn't mack with ease

It's in his coat, and this is what he wrote

Sickest flow without an antidote
