Zippie
A zippie is a person who does something for nothing. Any supporter of free culture, free food, free books, free software is a zippie.
The origin of the word is an evolution of the term yippie, which was coined by the Youth International Party in the 1960s. In subsequent years, zippie has arisen in reference to 1990s technopeople, in contradiction to yuppies. In the 1990s, Fraser Clark and others created a unique subculture that combined the "1990s techno hemisphere with the 1960s earth person". Zippies were thus advocates of PLUR, which originated on the alt.raves and alt.culture.zippies usenet groups.
