Someone who pontificates about subjects (especially science, especially climate
change) in the pub (or, even more likely, the golf club), while having no idea what they'
re on about. Typically to be found drinking gin and tonic, wearing a blazer, calling
people "squire", playing golf, and driving a Jaaaaaaag.
"All this
global warming nonsense. The Romans grew grapes in
Yorkshire! Explain that!"
"You'
re right, Ken. Several thousand climatologists and many petabytes of hard evidence can't stand up to a single well-informed gintellectual."
