Across diverse literary works, the word "spunk" emerges with a wide range of meanings. In some texts it denotes lively guts or courage, used to describe characters exhibiting bold determination and energetic resolve—as seen when spunk is equated with bravery or the direct spark of life ([1], [2], [3]). In other passages, especially in colloquial dialogue, it takes on a dismissive note, suggesting a lack of pluck or even being compared to something as insubstantial as a wet rag ([4], [5], [6]). Notably, the term also functions as a descriptor in more explicit or erotic contexts, where it conveys sexual fluidity or raw desire ([7], [8], [9], [10]). Additionally, regional and historical variants of the word underscore its versatility, being employed both metaphorically for creative energy or moral courage and literally to denote physical combustibility or spirited force ([11], [12], [13]).
