Usually capitalized, but may appear as ‘abend’. Hackers will try to persuade you that ABEND is called abend because it is what system operators do to the machine late on Friday when they want to call it a day, and hence is from the German Abend = ‘Evening’. 2. [alt.callahans] Absent By Enforced Net Deprivation — used in the subject lines of postings warning friends of an imminent loss of Internet access.
