A person who actively rejects and opposes established social customs and conventional ways of thinking and behaving.
From anticonventionalism + -ist (person). This person-label emerged in cultural criticism when critics needed terms for artists and thinkers deliberately breaking with tradition.
An anticonventionalist might wear shocking clothes, create bizarre art, or challenge social taboos—but interestingly, artists who are anticonventionalists often become famous and celebrated, which makes them part of a new convention.
