Poetry isn't just for elves, Orcs also write poetry. Orcs write about everything people write about, only through their particular evil and bloodthirsty vision. Born to evil, we find poetic orcs writing of love and beauty, at times reaching upwards, and at other times raging against the delicate and refined.
A sample from "Orcish Poetry":
Elfie Elfie
flower and tree
leaf and rosy
unlike me
Gnash and smash
tear with claw
bite and bite
until bony raw
