Hoi Polloi

The English expression "(the) hoi polloi" was borrowed from Ancient Greek, where it means "the many" or, in the strictest sense, "the people". In English, it has been given a negative connotation to signify the common people. Synonyms for hoi polloi include "the plebs" (plebeians), "the rabble", "the masses", "the great unwashed", "the riffraff", and "the proles" (proletarians). (Wikipedia)
