MU
A misunderstood word, meant to cause everything from blows (sudden departures) to overts and withholds, and actually being the root cause of SPs. Because of the centricity of "MUs" and their destructive potential it is a crime to go by them when studying, and subjects the student to the risk of getting a kangaroo "court of ethics". The cult is fanatical about not going by one, and insists that everyone look things up endlessly in dictionaries and go through every definition. This becomes quite tedious with words like "to", "set", and "be." Extensive pieces of the "tech" are devoted to "word clearing", qv, and so the hapless student ends up trapped in a arbitrary system which may punish or help, punish or help, alternately with the word clearing or the ethics actions. The very definition of "MU" is mutable and arbitrary in that it is a word that makes one frown or blink or stumble on or slow down on reading, etc., as spotted by others - all of this adds to the coercive, conforming, and group-pressure nature of the beast.
