scheister Saw this word this morning intended to mean some sort of bad person, probably a fraud or huckster from the context. The only other place I could find it was in a post in the French-English forum, where it apparently meant a thief or embezzler. I thought perhaps my friend meant to say either shyster or keester, but neither fits. Here is the sentence: We need the free speech. We need to let scheisters sink or swim by themselves.
