   loss
      <jargon> Something (not a person) that loses; a situation in
      which something is losing.  Emphatic forms include "moby
      loss", and "total loss", "complete loss".  Common
      interjections are "What a loss!"  and "What a moby loss!"
      Note that "moby loss" is OK even though **"moby loser" is not
      used; applied to an abstract noun, moby is simply a magnifier,
      whereas when applied to a person it implies substance and has
      positive connotations.
      Compare lossage.
