If you call someone Blimpish, you are saying they think like a pompous old man with political ideas from another century — stiff, proud, sure that the old ways (and often the old empire) were best, and not very interested in anyone who disagrees. It is not a compliment; the word is there to show disapproval. It usually points at an older man, or at talk that sounds like one. You meet it in British newspapers and books more than in everyday student English. Though actually, it comes from a cartoon character, Colonel Blimp: a fat, red-faced British officer full of loud, old-fashioned opinions. Blimpish means “like that colonel.” The same word blimp is also the name of a kind of airship, and the character was named with that picture of something puffed up. When people say Blimpish, they almost never mean a balloon. They mean the attitude.
