Reference to the sphinctorial area of a cat as it faces away from you with it's tail high in the air. The tight puckered area that is staring you straight in the face as your cat turns and walks away from you as you were petting him/her.
Occasionally there will be a little left over crust on your cat's "onion ring" causing it to further resemble the onion rings from your favorite fast food establishment.

I was petting my cat, when all of a sudden he turned around and raised his butt high in the air, giving me full frontal view of his ONION RING that I didn't want. He waved his kitty ONION RING back and forth before he finally walked away. I don't have that cat anymore, sorry PETA.
