Moof-milker

Moof-milker, also spelled moof milker, was an insult used in the galaxy, referring to a stupid person. The corresponding adjective for the insult was moof-milking; when Looti Vario attempted to divert a contingent of Imperial stormtroopers while he and his companions attempted to flee from Janix, he shouted, "Over here, you moof-milking laser brains!"

There were actual individuals who milked moofs, which inspired the term. A similar insult was "nerf herder," which was also formed from the name of a livestock animal paired with a corresponding form of animal husbandry.
