Alright, here is my comeback bro.. 20 lines....
Lets see if its good enough....

Yo....
This faggot thinks hes got me beaten, what a pity,
he reminds me of a toilet cause his whole verse was shitty,
Be set for a defeat, fact is, you wanna-be-me,
but you song cant be played, like a scratched CD,
turn you into you're mother, nice big-and-beefy,
believe me, its easy, to defeat you no point in mis-leading
ill just unlash my belt, hit you with lyrical-welts,
my shit sells, yet spitacular's shit remains-on-the-shelf,
pump holes in you-with-shells, and send-you-to-hell,
dont worry little bitch, i already got you're female,
night and day, your on you're knees, you pray-to-a-saint,
like please, oh please, cant Big D become gay-or-get-AIDS?
no way, cause you're woman's pussy is delicious,
and you cant take her back bro... unless you want siffilus,
yo listen, my flow will leave you with about eighty stitches,
cause ill cut you down to size like a jewish circumsizion,
cause this spitaculette, swallows so much ejaculate,
its fact-you-bitch, what the fuck can i attack-you-with?
how about the illest punchlines from Big D ever spat,
so it hurts more than when you're dad jammed his dick up youre ass...
