Well, actually, soup. I just read a FB thread about vocabulary gaffes. One poster cited hosting a client for lunch. As the guest ate his cold tomato soup, he remarked that it was his first time having Gestapo Soup.
Just hope the main course wasn’t goose…
One of my favorites was overhearing a dude talk about Indian food and a place that had great ‘chicken tiki marsala’
My father in law used to say he wanted gazpacho when he wanted carpaccio.
