Michael Bywater uses this term in Lost Worlds (2004 - which isn’t about language but often touches on it) to describe overblown phrases for ordinary things and he gives the example Recycling Operative for dustman. He is actually talking about the term Specified Tertiary Education Providers (Steps) which he says will replace “universities” in Scotland soon.
I googled “descriptor bloat” (with speech marks) and got one hit from a highly technical computer site. (Bywater is also a tech Apple geek and blogger as he admits in Lost Worlds and he wrote video games with Douglas Adams, and now teaches classical lit at Cambridge when not writing acerbic newspaper columns.)
Has anyone else come across this term? Can a contemporary term exist and not be googlable?
(I reckon he lifted it for his own purposes and would be delighted to admit this (read his book!) and that it does the job admirably.)
