okay i'm hoping that somebody pray for me
I'm praying that somebody hope for me
I'm staying where nobody 'posed to be
p-p-posted
being a wreak of emotions
ready to go whenever just let me know
the road is long so put the pedal into the floor
the enemy's on my trail
my energy unavailble
Imma tell em hasta luego
they wanna plot on my trot to the top
I've been outta shape thinking out the box I'm an astronaut
i balsted off the planet rock to cause catastrophe and it matters
more because i had it not
had i thought about wreaking havoc on an opposition
kinda shocking they wanted static
with precision i'm automatic quarterback
i ain't talking sacking pack itpack it up i don't panic
who the baddest it doesn't matter cause we at ya throat
