BAe 146 was dubbed the "whisper jet", mainly it is said because it had nothing to shout about.
I think that the 748 was called the Budgie by BA originally, rather a spotter term, in the latter years of service when the elderly airframes were converted to freighters and received minimal maintenance, they were referred to by engineers in terms that cannot be repeated on this forum.
Herod, the airframe systems on the F27 were simple, easy to maintain, reliable and foolproof, the 748 didn't manage any of the above, the best thing about it was the engine.
Nicknames for aircraft seems to be more of a military thing, I spent many years on a type known as t' Therald by BIA staff up north, and the 'Erald by BAF at Southend.
