has the X nature [seems to derive from Zen Buddhist koans of the form
   "Does an X have the Buddha-nature?"] adj. Common hacker construction for
   `is an X', used for humorous emphasis. "Anyone who can't even use a
   program with on-screen help embedded in it truly has the {loser}
   nature!" See also {the X that can be Y is not the true X}. See also
   {mu}.
