    Note: It’s an American idiom and started as “hand over hand.” It’s a nautical saying about climbing the rigging of a ship. By the 19th century, it had evolved to “hand over fist,” and was used to refer to taking in something, like money, rapidly. We can also say, “Business was bad and we were losing money hand over fist,” as it’s a neutral term meaning “speedily, increasingly, at a tremendous rate.”
