Why I do not Ham on Rye it

You cannot borrow steal or buy it.
Sumo wrestlers never try it.
Female starlets do or die it.
Vitamin makers fortify it
You never cookie, cake or pie it.
Pizza parlors terrify it.
Now and then I me oh my it,
but I hope I don’t defy it,
for if I ever hope to guy it,
I simply must stay on my diet!

For dVerse Poets, a poem of negation.
