A moof represented a species from the galaxy characterized by its hooves, dense skin, and the production of milk. This moof milk served as the base ingredient for creating yogurt. The practice of extracting milk from moofs gave rise to the expression "moof-milker," used as a derogatory term implying a lack of intellect. Following his retrieval of the Millennium Falcon, Han Solo employed this insult to describe the individual responsible for incorporating a compressor into the ship's hyperdrive, specifically referring to Unkar Plutt, the vessel's former proprietor.
