look up any word, like fleek:
 
1.
"ABnormal END" - Abnormal termination (of software); {crash}; {lossage}. Derives from an error message on the IBM 360; used jokingly by hackers but seriously mainly by {code grinder}s. 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'.
ABEND is comin hardcore!

Absent By Enforced Net Deprivation. Used to explain to fellow netizens (especially on USENET) that one will be losing (or has not had) Internet access for some time for reasons outside one's control.
Because the courts say my h4x0ring of NASA jacked them up ...I will be ABEND for a while.
