A follower of Hedonism which preaches that the greatest good in life for mankind is the pursuit of pleasure. Personal indulgences become their only aspirations. Most of this theory and its followers were
rejected through
logic hundreds of years ago but
high school goths and wannabe pseudo-intellectual philosophers often adopt it to feel different from others. It served as the basis for Utilitarianism. In modern slang it most often is synonymous with devil worshippers.
Little Billy was picked on and had his
feelings hurt so instead of sucking it up and becoming a man he dressed all in black, becoming a hedonist to
make him
feel special.
