Long pig is an antiquated term for human flesh, eaten by cannibals. Purportedly, the term long pig is a translation of a phrase used in the Pacific Islands for human flesh intended for consumption. Early explorers and missionaries who contacted cannibal Pacific Islanders were told that human flesh tasted similar to pork, thus the term long pig.
The popularity of the phrase long pig was greatest from the 1880s to 1920s, a time when many Pacific Islanders were first contacted and studied.
