Idk...My rap?

I'm a playa like Dave Beckham,
a football champ,
My failures will keep you hoping,
Like 1st of the month foodstamps,
Step back,
take that,
like 1,2, ta the head,
My lyrical bullets will make you feel null and braindead,
'cause you dont have the capability,
like infertility,
to come back with an insult,
that would truly get to me,
So You want some of this?
then take a shot,
cause im invincible,
just like that song by 2pac,
so take some notes and listen,
cause when i spit,
my metaphorical polish goes to work making this mic glisten.
