Dutchman
.Iʹm a Dutchman if I do. A strong refusal. During the rivalry between England and Holland, the word Dutch was synonymous with all that was false and hateful, and when a man said, “I would rather be a Dutchman than do what you ask me,” he used the strongest term of refusal that words could express.
Well, Iʹm a Dutchman! An exclamation of strong incredulity.
