mess-dos

from Jargon File (4.4.4, 14 Aug 2003)
mess-dos
 /mes.dos/, n.

   [semi-obsolescent now that DOS is] Derisory term for MS-DOS. Often
   followed by the ritual banishing "Just say No!" See {MS-DOS}. Most
   hackers (even many MS-DOS hackers) loathed MS-DOS for its
   single-tasking nature, its limits on application size, its nasty
   primitive interface, and its ties to IBMness and Microsoftness (see
   {fear and loathing}). Also mess-loss, messy-dos, mess-dog, mess-dross,
   mush-dos, and various combinations thereof. In Ireland and the U.K. it
   is even sometimes called `Domestos' after a brand of toilet cleanser.
