Originally, in Old School Hip-Hop, the term 'freestyle' referred to a pre-written rap verse that was not on any particular subject matter and was just written for the purpose of demonstrating skill.
So that's what this is.

Thanks Haywyre for making the awesome beat. http://haywirehaywire.new grounds.com/

Lyrics below:

My brains are buzzin,
thinking of nothing other than percussion
and words, spit in verses over something bumpin
Jumpin to conclusions: I'm losin it,
Too true, and I'm proving it,
Like water in my hands dripping through, but I'm movin
On to something better, or so I think, I'm shrinking,
Never in sync with myself, It tells me that I'm sinking,
Past what I'm thinkin, the blast got me seekin past the beacon,
That shines and has me blinded, blindsided, till I'm weakened,

Til now I've just recovered best I could, and rest I would,
The jester was tested, not the best, but good,
the rest wrestle with shoulda, never did it but coulda
Something along the lines of a lion with no teeth

It's fine, to me, beast is something easy to be,
An artist with an easle, monkey swingin tree to tree
Vine's a margin, lines of marchin soldiers never retreat,
Extra fleets make it the best defeat you ever did see.

Instead of whining, I'mma try to pick the rhymes up and might,
just stay a while, and you know I'll make sure the rhymin is tight
the timings right, to line up the mics, consignin the blights
to bite it, and if they fight it we strike, we find what's wrong and we right it,
20 20 sighted, strong for a white kid,
compared, my lightning makes you no longer exciting
Get my triton, my pitchfork in my right hand,
delightin writer's fightin for the right of words
What you heard, is a fiction perpetrated by haters,
take their papers, burn em, turn em into lessons for later
Adjust the flavor, change it for a change of pace, and savor
The taste, there's nothing greater, great, is what we're made of
fakes, are gettin ate up, it's crazy, what I can make up,
Shake down and I will shake up, you'll hate it I never gave up.

Offer a bounty for astounding challenges to my flow,
Shout me and I'll be there toutin resounding talent that grows up out me
