A person in their later stages of life (senior citizen) who experiences or exhibits a renaissance of freedom, creativity, and social engagement similar to those usually present in a person's teenage years. Often characterized by sudden obsession with life-long background/dream interests (dancing, sailing, antique cars, beauty, art) and joyful but troubling carelessness and wreckless socializing.
My 70 year old mum is acting like a total seenager, dancing 7 days a week, listening to loud salsa music and constantly obsessing over her latest boyfriend.
