Sentence:  Judge May: He's what? / John Cedar: What was that you said he was? / Jane: Pixilated. / Amy: Mm-hmm. / John: Now that's rather a strange word to us, Miss Jane. Can you tell the court exactly what it means? / "Board member": Perhaps I can explain, your honor. The word "<WSD>pixilated</WSD>" is an early American expression derived from the word "pixies", meaning elves. They would say the pixies had got him. As we nowadays would say, a man is "barmy". 
Meaning of the word marked with <WSD> tags:  behaving in an eccentric manner, as though led by pixies.
