This is a song about "Mr chest"

On the streets all apeshit..bangin chest to chest

I confessed bein' atheist, they said i was possessed

I feel a sharp pain in my chest,

Smoking khaled, my weed the best

I'm a 417 with a bulletproof vest

Overflow of dope to your chest

Mr. prezy, where head be

Ridin’ round, and this bitch dirty

Niggas who be rapping how real they are

You be tapping like a mr

In pajamas i snuck out to watch santa

Aka mr. louisiana.

Throwin you a dub

Mr. right's running up,

Painful indigestion in my chest

That happen to act like a black president
