High on the hog

An allusion to the best and costliest cuts of meat from a hog, considered to be parts above the belly such as the loin, rather than lower parts such as the feet, knuckles, hocks, belly, and jowls. US, late 1800s; popularized 1940s. The variant forms – live/eat and on/off – are attested since at least the 1930s. However, decades earlier is the phrase on the hog, originally on the hog train meaning someone living on little expense.
