Blimpery

(British) A stereotype of a pompous, ex-military middle-aged man, conservative and opposed to new ideas.

Blimp mode is the state of being fully locked into pompous, reactionary, out-of-touch blowhard behavior — puffed up with opinions nobody asked for, convinced that everything was better before, and constitutionally unable to entertain a new idea. Borrowed from Colonel Blimp, the British satirical archetype of the blinkered establishment reactionary, blimp mode names the gear someone shifts into when they start pontificating about declining standards, the youth of today, or whatever cultural change they've decided is civilization's death knell. Often entered without warning at dinner tables and office meetings.

Blimp coded describes someone whose every opinion, mannerism, and aesthetic choice screams Colonel Blimp — the pompous, reactionary, deeply establishment British type who has decided that their era was the correct era and every subsequent development is a sign of decline. It's baked into how they dress (tweed, club ties), how they talk (booming, uninterruptible), and what they believe (everything was better before, standards have collapsed, and someone needs to say it). Being blimp coded isn't necessarily malicious — it's more a form of ideological fossilization worn as identity. Often used in British political and cultural commentary.

Being blimp pilled means you've swallowed the worldview — that things are in decline, that the old ways were better, that modern sensibilities are a collective delusion, and that someone with your clarity of vision has a duty to say so at length whenever the opportunity arises. The '-pilled' suffix signals a completed ideological conversion, and in this case the ideology is Colonel Blimp's: a brew of nostalgic conservatism, establishment entitlement, and a serene inability to take criticism. Can be used self-mockingly by people who are aware they're drifting in this direction, or accusatorially at those who aren't.
