write-only language

( n.)

   A  language with syntax (or semantics) sufficiently dense and bizarre
   that  any  routine  of  significant size is automatically {write-only
   code}. A sobriquet applied occasionally to C and often to APL, though
   {INTERCAL} and {TECO} certainly deserve it more. See also {Befunge}.
