The armadillo (the little armored one) has had many nicknames. “Hoover Hog” was originally applied to the jackrabbit after Herbert Hoover’s Great Depression, but the nickname was also applied to the armadillo. “Poor man’s pig” or “poverty pig” also describe the armadillo as a dish for those who can’t afford better.

Called “Hoover Hogs” and “Poverty Pigs” during the Depression, armadillos are eaten by quite a few Southerners, although armadillo-lovers cannot seem to agree on whether they taste like pork, rabbit or venison.
