The nickname "john" for the toilet is believed to originate from the 19th-century popularity of the name "John" as a generic term for a man, similar to "Joe" or "Jack." One theory suggests that it derives from John Harrington, who invented the first flush toilet in 1596. Additionally, public restrooms often used "John" on signs, making it a common euphemism. The term has persisted into modern usage, becoming a colloquial term for the toilet.
