Dewaism is a way of thinking or utterance that expatriates from your country show, when they tell you how shit, disorganised or barbarian your country is, by implying or denoting that the countries they live in are far sperior to yours. The word 'dewa' comes from the Japanese postposition 'in', with which they begin a sentence, for instance, 'In France (France dewa), no males would do such a vulgar thing, but you guys do. How low!'
'In America (America dewa), no one gets drunk as you do in your country. How third-world!'
'We're all fed up with your dewaism, John.'
