Here's another somewhat brief trivia question for your enjoyment.
Continuing with the current theme of places and names, today's trivia is about phrases that carry a nationality, like Dutch uncle. These are decently common in certain registers of English, and often carry some sort of insult to the country involved. Dutch uncle, along with Dutch courage and some more obscure examples, comes from the 17th-century Anglo-Dutch Wars, when anti-Dutch sentiment was running high. Other such phrases have more obscure etymologies, like Russian roulette. (These terms are an interesting opposition to freedom fries, a euphemism in which the nationality was dropped due to anti-French sentiment.)
Your challenge: name a two-word phrase starting with a nationality which is also an eggcorn - a term whose etymology includes some kind of misinterpretation.
