A chum just sent me an e-mail message in which he explained his absence from the net for a few days by saying that a parasite got into his computer and it "went kafluey." I have heard this word a number of times, usually in connection with machinery which is misbehaving, and always in a form like going kafluey, gone kafluey or went kafluey. Surely this is not a dictionary word but, just as surely, I know what it means.
