Similarly, a "gay cat" was a young male apprenticed to an older hobo and commonly exchanging sex and other services for protection and tutelage. The application to homosexuality was also an extension of the word's sexualized connotation of "carefree and uninhibited", which implied a willingness to disregard conventional or respectable sexual mores. Such usage, documented as early as the 1920s, was likely present before the 20th century, although it was initially more commonly used to imply heterosexually unconstrained lifestyles, as in the once-common phrase "gay Lothario", or in the title of the book and film "The Gay Falcon" (1941), which concerns a womanizing detective whose first name is "Gay". Similarly, Fred Gilbert and G. H. MacDermott's music hall song of the 1880s, "Charlie Dilke Upset the Milk" – "Master Dilke upset the milk, when taking it home to Chelsea; the papers say that Charlie's gay, rather a wilful wag!" – referred to Sir Charles Dilke's alleged heterosexual impropriety. Giving testimony in court in 1889, the prostitute John Saul stated: "I occasionally do odd-jobs for different gay people."
