I think there is. Let me outline what I mean:
1. Permission-granting. Writing a bad poem allows me to do things I would never do in a "good poem." It allows me to write in the first place, for one thing. I don't have to worry about talent or the lack of it. I am immune from criticism. The worst they can say is that my poems are not bad enough.
2.Humor is built into the process. I am a funny guy.
3.Voice. I don't have to be myself in a tedious way, or try to occupy someone's idea of a poetic speaker's identity. I can be myself easier in a persona, even if it is only slightly different from my own personality.
4. A lot of poetry fails from trying too hard. You'll never find me doing that. Ars est celare artem.
5. At the same time, I can sneak in any "good" poetic effect I want to.
Because I bought whisky
they think I want to buy more of it
and special glasses for it
I see fine with the glasses I already have on
Like any petit-bourgeous Latin American man
I published a slim volume of verse in my twenties
I had a girlfriend named Geraldine
She was warm-hearted; her make-up was immaculate
She was easy to write love poems for
Nothing was extraordinary about me; I was good-looking
But isn’t everyone at that age?
Now I look back on those days and I miss Geraldine
Though I am still married to her
