Un-Learning is a good expression in English because it is not commonly used. Anything that is irritating and surprising in the general use of language and familiar patterns of thought is suitable for unlearning something.
I have here an excellent example of Alan Watts talking about Zen methods and the form of expression of the masters who irritate, provoke and surprise their students with behavior without which a person would get stuck in his habit.
A short story (which I believe is not mentioned here in the audio lecture): A European who wants to gain knowledge and is in search of the truth visits a Buddhist monk in his monastery. There's a welcome tea. The monk begins to fill the cup of his visitor, but he does not stop pouring and as the liquid flows over the edge, the visitor says frightened: "Stop, you must stop, it all goes wrong!". The monk answers: "As tea no longer fits into the cup, so are you full of knowledge that nothing goes into."
