A philosophy, belief, or behavior pattern characterized by obsolescence or becoming extinct; adherence to extinct or outdated ideas.
From 'dodo' plus the suffix '-ism' (denoting a system of beliefs or practices). A neologism created by analogy with other '-ism' words, treating 'dodo' as a source of philosophical or behavioral systems.
Creating '-ism' words is how English speakers turn anything into a philosophy—'dodoism' is the wry observation that some beliefs, practices, or even people are heading toward extinction. It's satire baked into a single word.
