/mes-dos/ (Or Ms-DOG, Messy-DOs, mess-dross, mess-loss, mush-dos) Derisory term for Ms-DOs. Often followed by the ritual banishing "Just say No!" Most hackers (even many Ms-DOs hackers) loathe Ms-DOs for itssingle-tasking nature, its limits on application size, its nasty primitive interface, and its ties to IBMness (see fear and loathing). In Ireland and the UK it issometimes called "Domestos" after a brand of toilet cleanser. [Jargon File] (1994-11-16)
