Playability
Playability is a term referring to how open or willing a hostess is to engage in flirtatious or more intimate behavior with customers. It is a general measure of how much "fun" or entertainment the customer can expect from the hostess, often involving things like playful touching, sitting on laps, and sometimes more provocative behavior. Higher playability suggests that the hostess is more willing to entertain the customer, while lower playability indicates a more reserved approach.
A nightlife venue like a KTV will have a playability rating, which reflects the average playability of the girls at the venue. However, the true playability of any individual depends on her and her personal interest and connection with you.
