quirk

This term describes a deviation from the expected norm, whether in human behavior or situational outcomes. When applied to personality, it suggests a harmless eccentricity that makes a person unique rather than a pathological flaw. It carries a lighthearted, often whimsical connotation. In the context of fate or events, it implies a random, unpredictable shift that alters a trajectory. Physically, it refers to a sharp, sudden change in direction or shape, mirroring the conceptual "twist" found in its behavioral and situational meanings.
