 /den'troh/

   [{demoscene}] Combination of {demo} (sense 4) and {intro}. Other name
   mixings include intmo, dentmo etc. and are used usually when the
   authors are not quite sure whether the program is a {demo} or an
   {intro}. Special-purpose coinages like wedtro (some member of a group
   got married), invtro (invitation intro) etc. have also been sighted.
