(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)
