“Big Five" most commonly refers to either the Big Five African Safari Animals (Lion, Leopard, Rhino, Elephant, Buffalo) or the Big Five Personality Traits (OCEAN) in psychology (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism), both grouping essential characteristics into five key categories. The safari term comes from hunters finding them difficult to track, while the psychology model provides a broad framework for understanding human personality.
