   2. (Golf) a score one stroke over par for a hole; formerly,
      the definition of bogey was the same as that now used for
      {par}, i.e., an ideal score or number of strokes, for each
      hole, against which players compete; -- it was said to be
      so called because assumed to be the score of an imaginary
      first-rate player called Colonel Bogey. Now the standard
      score is called {par}.
