A person who believes that pleasure and enjoyment are the most important things in life and actively pursues them.
From Greek 'hedonē' (pleasure) plus '-ist' (one who practices or believes), likely first used in English in the 18th-19th centuries as philosophical discussions became more personal and individual.
Calling someone a 'hedonist' used to be a serious insult questioning their moral character, but modern psychology actually shows that people with some hedonic motivation are often happier and more psychologically balanced.
