The quirk that makes you you, not a diagnosis, just a fingerprint.

means A particular way of thinking or behaving that belongs distinctly to one person, not shared or standard.

from From Greek idiosynkrasia, built from idios ('one's own, private' — the same root in 'idiom' and 'idiot') plus syn ('together') and krasis ('a mixing, blending'). Ancient Greek medicine used it for a person's unique blend of bodily humors — the private mixture that made your temperament yours alone. The word kept that sense of 'personal blend' even after humor theory faded, settling into English to mean a trait peculiar to an individual rather than a universal rule.
