Gay—Originally meant (13th century) "lighthearted", "joyous" or (14th century) "bright and showy", it also came to mean "happy"; it acquired connotations of immorality as early as 1637, either sexual e.g., gay woman "prostitute", gay man "womanizer", gay house "brothel", or otherwise, e.g., gay dog "over-indulgent man" and gay deceiver "deceitful and lecherous". In the United States by 1897 the expression gay cat referred to a hobo, especially a younger hobo in the company of an older one; by 1935, it was used in prison slang for a homosexual boy; and by 1951 and clipped to gay, referred to homosexuals.
