This is a song about "The brain"

I am marvin with mind, but i listen to wayne

I'm the fuckin' menace inside everyone's brain

And i move across your membrane, you loose against my insane

Burn't, can't afford any strains / of the herb which'll open my brain

She my billie jean we menage with mary jane

Take this bullet of lyrical rhymes right into the brain

Aimin' at them skin headed bitches let it rain

The fucked up shit that goes on in my brain

Whos brain seems to burst by the seams

Spit selvage my nigga, it's in my jeans

Enough to drive a man insane, a woman insane

A bargain against the arsonist's sicko brain

Down in dallas at the all-star game

Put my calling card, through the side of your brain.
