go the whole hog

Etymology
Likely a folk term from the practice of livestock and butchery; “whole hog” or (“snout to tail”) refers to letting no portion of the animal carcass go to waste. For example, skin is tanned for leather, sweetbreads are harvested, and commonly cast off pieces such as hooves are pickled.

The phrase the whole hog appears in ’s 1779 poem “The Love of the World Reproved”, a poem teasing Muslims about suggested ambiguity over their religious prohibition on eating pork. By 1830 the phrase had become popular across America, being used in newspapers and political campaigns. At this time it migrated across to Britain, where the phrase was adopted.

Verb

 * 1)  To do something as entirely or completely as possible; to reserve or hold back nothing.
