Yet Another
 adj.

   [From Unix's yacc(1), `Yet Another Compiler-Compiler', a LALR parser
   generator]

   1. Of your own work: A humorous allusion often used in titles to
   acknowledge that the topic is not original, though the content is. As
   in `Yet Another AI Group' or `Yet Another Simulated Annealing
   Algorithm'.

   2. Of others' work: Describes something of which there are already far
   too many. See also {YA-}, {YABA}, {YAUN}.

Yet Another
YA-

   <jargon> (YA-, after {Unix}'s {yacc} - Yet Another
   Compiler-Compiler) A humorous allusion often used in titles to
   acknowledge that the topic is not original, though the content
   is.  As in "Yet Another AI Group" or "Yet Another {Simulated
   Annealing} {Algorithm}".  If used of others' work, it
   describes something of which there are already far too many.

   In hackish acronyms the "YA" prefix almost invariably expands
   to {Yet Another}, e.g. {YABA}, {YAUN}.
