(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)
