Manges
"Until 1920 the rebetika were sung exclusively within the underworld. This urban subculture was a segment of the lowest socieconomic class in Greece, and its members were known as rebetes or manges. Though it is difficult to define a rebetis or a mangas, it can be said that he was a person who lived outside the accepted standards of the traditional Greek society, and who showed contempt for the establishment in all its forms."
