Is it true that in the southern states....?

its true, tho ive never heard the phrase myself.

seems its a dish, too!

Possum on the Half Shell (Armadillo)

2 lb Armadillo meat

1/2 c Margarine (1 stick)

Salt (to taste)

Pepper (to taste)

Lemon juice (to taste)

Season meat with salt, pepper and lemon juice; rub with margarine. Wrap in foil; bake at 325 degrees for 45 minutes. Remove foil; add more butter and brown.

It's an old expressing describing them. Since armadillos live in the southern states from Florida west to the deserts of the Southwest, that were people talk about them.

That sounds like the deep South, where everything's either ****** or eaten or both.
