From the PK Dick short story Autofac, where the word 'pizzled' is used to confuse a robot who keeps delivering unwanted milk. Since there is nothing wrong with the milk, the robot will not stop delivering it, even though the humans don't want it. But when the humans say that it is 'pizzled', the robot is forced to fill in a compaint form which ultimately results in the downfall of the robot factory system.
