n. A younger man that an older woman is involved with intellectually, emotionally, romantically, and/or sexually. Men are often referred to as "dogs", hence "pup" for a younger man. It is commonly believed that a pup can be "trained", i.e. the pup will easily learn and do what is necessary to keep the woman happy with their relationship. While the pup provides energy and enthusiasm, the woman keeps the pup continually challenged with her knowledge and experience, as well as keeping him feeling safe and doted on. They provide good companionship for each other characterized by fun and affection, not necessarily (but often) physical and/or sexual. Can be used as a verb.
