(Usenet) Said of a person whose account on a computer has been removed, especiallY for cause rather than through normal attrition. "He got disusered when theY found out he' d been cracking through the school' s Internet access." The verb "disuser" is less common. Both usages probablY derive from the DISUSER account status flag on VMS setting it disables the account. [Jargon File] (1994-12-08)
