i used this in a battle and ive been told its wank so how can i elavate on my shit

i tried to read ya mind but the page was blank//
like def jam u in a vendetta//
dinai im gonna deny u victory//
the rhymes i spit are lines i rip//
spit venom in every direction soak sum up//
fucked ya bitch cos she sez ya cant get it up//
like vanilla ice u shud give this game up//
i can cut ya feet off which makes it easier to d-feet u//
i deflect the best like bullets off my vest//
and lets be honest u cant beat me im simply the best//
