mid-16c., from Gk. kynikos, lit. "dog-like," from kyon (gen. kynos) "dog." Supposedly from the sneering sarcasm of the philosophers, but more likely from Kynosarge "Grey Dog," name of the gymnasium in ancient Athens where the founder, Antisthenes (a pupil of Socrates), taught. Diogenes was the most famous. Popular association even in ancient times was "dog-like." For nuances of usage of cynicism, see humor.
