What do you think of this poem-dlp?

Leave 'arenas,' it makes more sense. But so does "warthogs AND jackals." You wouldn't want to offend either group by excluding them. And, call me old-fashioned, I prefer using the hyphen in between the two parts of compound words such as meat-rending and razor-tongued. I think it has more dash, as they say. But you definitely get ten points for "fetid tumescent narcissism." I would opine that the very style of that phrase - overblown, pretentious, and reveling in that which is gross - reveals that you are (as I am) clearly a member of that coterie, Next time try for the inclusion of mephitic - or, at the very least - pustulant. They are two of my faves.
