Ο ΟΡΙΣΜΟΣ ΤΟΥ ΖΑΜΑΝΦΟΥ !!

Zamanfou, also known as "ochaderfismos" (Greek "Ωχαδερφισμός") is a counterculture phenomenon in Greece which involves social loafing as its principal characteristic.

Although Zamanfou might be considered a social phenomenon in Greece, it is no different Social loafing, as this appears in other cultures or epochs. The individualism expressed by it results in many different stances and attitudes, depending on economic and cultural provenance, education level, political beliefs, and age of their perpetrators.

Within the Hellenic Armed Forces a form of zamanfou has developed, called loufa. It is yet another expression of the social loafing phenomenon as practised within the armed forces. Loufa, unlike Zamanfou, is practised covertly by conscripts who may be held accountable for their actions.
