Hoi,
I have been a developer on midrange computers, my speciality was Synon/2, CLP and RPG/400. That and system management. I was responsible for backup and recovery for companies listed on the stock exchange. I ended up being CISSP certified. Anyway at some stage my chef was told that a system showed "unexpected behaviour" when a function failed spectacularly. His reaction: "I do not care for euphemisms, why did it fail". He listed a large number of failure types.
Using euphemisms in this way, is talking down on the "unwashed".
Thanks,
GerardM.
