Yo, Everyone...Tell me what you think of this freestyle

Yo, time to enter class son...
Im tha teacher in this class, I got a degree in pain
When your rippin on the boards your under my regin
They call me Casper cause im white
This is true but at least i can put up a fight.
Been rollin with the best rappers in town/
5 of the hardest throwing 'em down.
I haven't been challenged by anyone yet/
If winning battles were wars I be a Vietnam vet
Poppin a nine like i be poppin a rhyme.
I make other rappers spit thru wires like Kayne
I'll be like Frank Sinatra and do it my way!
Reppin the East Coast and dissin the west
Ya wanna roll son your messin with the best!
So thats it end of the fu*king story
I'll be going out in a blaze of glory

Respond tell me how you think it is
