Shyster is derived from the German term scheisser, meaning literally “
one who defecates,” from the verb scheissen, “to defecate,” with the English suffix -ster, “
one who does,” substituted for the German suffix -er, meaning the same thing.
Generally used to describe someone who is untrustworthy, money grabbing and full of
crap, particularly in the field of legal work for some reason.
