Jingoism is an ill-defined word these days. It originates from the phrase "by Jingo" which is a euphemism for "by Jesus", kind of like "oh my gosh" = "oh my god". The phrase "by Jingo" was used in a nationalistic British drinking song and made in into the current lexicon by virtue of it's esotericism. Most people don't really know what it means but have get a negative feeling from it because of current usage. Anyway, I don't like the word Jingoism.
