my old dutch

The phrase "my old Dutch" is a colloquial expression used in British English to refer affectionately to a close friend, partner, or someone with whom one has a strong emotional bond. It is derived from the rhyming slang of the 19th and early 20th centuries, where "Dutch" rhymes with "hutch" and is short for "Duchess of Fife," a term used to signify one's wife. Hence, when someone refers to someone else as "my old Dutch," they are expressing fondness or endearment towards that person.
