Treat it as an (American-)English expression, and you'll feel better :-) Reminds me that when I was in central Germany, I saw that "Gulasch" is a food name everyone knows, except it didn't denote the heavy soup from Southeastern Hungary from which it took its name (gulyás), but a kind of stew (incidentally also a Hungarian dish, but called pörkölt).
