doot
  A person who is either about to go on jury duty or is already on a case, clueless about what goes on in criminal law procedures despite orientation in the waiting room and instructions from the judges.  Also spelled "dut", both spellings pronounced to rhyme with "boot".  From "jury DUTy".
  What a pain in the butt!  It's time for me to talk to that doot in front of me at the courthouse!
