The word "hoyden" is an old-fashioned term that is not commonly used today. It refers to a noisy, boisterous, and carefree girl or young woman who behaves in a spirited or tomboyish way. A hoyden may be perceived as lacking in proper manners or decorum, and may engage in activities that are typically associated with boys, such as roughhousing, climbing trees, or playing sports. The term is sometimes used in a pejorative or dismissive way, but it can also be used affectionately to describe a spirited and adventurous young woman.
