I can only give part of an answer. Petit bourgois - pooterish - from the Diary of a Nobody - pooter took himself way too seriously & thought his boring life would interest others. I am working on the bottle & the grouse
Thanks both.
I haven't got as good a version of Chambers as the Mysterons!
Should have remembered Pooter but it is a long time since I read the Diary of a Nobody.
