Ageplay or age play is a form of roleplay in which one or more individuals acts or treats another as if they are a different age. The term may describe a variety of roleplaying that involves a difference in age; in practice, however, ageplay usually involves one or more adults acting as young children. Ageplay generally focuses on the age aspect and its involvement in the roleplay, such as highlighting youthfulness, immaturity, or the taboo nature of one's age. Ageplay may include sexual interactions, but not necessarily.
