A kipper is a very British term. A fish, usually a herring, preserved in salt and then smoked. Kippers seemed to be a popular breakfast dish at one point and presumably were very practical and long lasting. I don’t really remember them growing up in New Zealand, as we don’t have herrings for a start and fish smoked to a leathery quality was not so common. So, I suspect, kipper is a word that is not well known to much of the English speaking world.
Now there is a reminder of them in the term Ukipper which you see in articles about British politics. It refers to a member of the UK Independence Party which was one of the leading protagonists in Brexit or the idea of getting Britain out of Europe. Ukippers are regarded as having very particular views that often cause mirth or exasperation in others.
Did you know that Gaz is a Ukipper? Saw him being interviewed at a meeting on television the other night!
