I'm wondering if there is a word for something that is both famous and infamous, depending on context.
An example, hopefully appropriate, is the Australian food Vegemite...
In Australia, everyone knows what Vegemite is, almost everyone has tasted it, and the majority of people eat it regularly. It's very famous within Australia.
By contrast, outside of Australia (particularly in the USA?), Vegemite has somewhat the opposite effect - it is somewhat well known as an Australian food, but almost no-one would eat it or look upon it favorably as they don't eat it as Australians eat it, and thus it tastes absolutely horrible. It's certainly well known enough to feature on TV shows like The Tonight Show with Jimmy Fallon, where even after being shown how to eat it correctly, Jimmy still didn't like it.
I would therefore loosely classify Vegemite as being both famous (to Australians) and infamous (to other countries). Is there a word for such an object?
