You cats spit raps that are not believable
Your raps don't bubble 'cause they're inconceivable
Real life 
O.G.'s don't even speak to you
In hip-hop's culture there's really no need for you
I'll bring the heat to you, when it comes to them glocks
Like Freddie 
Foxxx, I'm keepin two
I'm known for my scary feuds
That's why 
I'm called 
The Terrorist by the 
Daily News
I rarely lose, 
I'm known to rattle a cage
I'm known to throw rappers off the stage
Maybe it's a matter of age
But as a M
C I got no patience for some rappers these days
I'm not old skool, or new skool,
