In colloquial language, this nickname reflects a laid-back, casual personality that does not conform strictly to conventional social norms. 'Not quite one thing nor another, yet uniquely itself.' Additionally, it suggests that the person can be fun-loving but not childish (not silly, nor foolish); aiming to present an easy-going, lighthearted nature.
