Booty call refers to a late-night or casual sexual arrangement characterized by minimal emotional connection or commitment. This interaction typically serves immediate physical needs rather than fostering romantic attachment, often mediated through brief digital communication to initiate contact. Neurobiological research suggests such encounters may activate reward circuits involving dopamine release in the ventral striatum, though without the sustained oxytocin-mediated bonding observed in pair-bonded relationships. The phenomenon reflects a strategic mating behavior in contemporary hookup culture where individuals prioritize sexual access while avoiding relationship maintenance costs.
