Colonel Blimp

An older man who is pompous or irritable and adheres to an outdated ideology. The name comes from a British comic strip character that first appeared in the London Evening Standard newspaper in 1934. Primarily heard in UK. He's such a Colonel Blimp when he starts ranting about his views on welfare and the poor. Grandfather, if you don't change with the times, people will eventually think you're a Colonel Blimp. There's no working with that Colonel Blimp of a headmaster who always thinks he's right!
