A person who actively participates in or advocates for a counterculture; someone who deliberately rejects mainstream societal values.
From counterculture + -ist (suffix indicating a person who practices or advocates something). This neologism emerged in the 1960s-70s to describe individuals deeply committed to countercultural movements and their ideologies.
While 'hippie' and 'punk' describe styles, 'counterculturist' is the word for someone who is a true believer in rejecting the system itself—it's more serious and ideological, capturing the philosophical commitment rather than just the fashion choices.
