"Spunklube" is a term used in the adult industry to describe a specific type of porn video. The word is formed by combining two words: "spunk," which refers to semen or cum, and "lube," which is short for lubricant. This tag indicates that the content contains scenes where one partner's ejaculate (spunk) is being used as a lubricant for further sexual activities. This is often done by rubbing the ejaculate onto the body or sex toy before engaging in intercourse, anal play, or other sexual activities. The use of spunk as lube adds an element of spontaneity and intimacy to the scene. It's important to note that this is a specific niche within the adult industry and may not be to everyone's taste
