Gadz'Arts or Gadzarts is the nickname given to the students and the alumni of École Nationale Supérieure d'Arts et Métiers (ENSAM)- a prestigious university ( grande ecole) specialised in engineering.
Since the beginning of the institution, the students of the school perpetuate their own traditions and folklore, and organise themselves in a student society or union. They call themselves "Gadz'Arts", abbreviated from "Gars des Arts" ("Guys from the Arts", the school's nickname is the "Arts"). The "Gadz" folklore includes traditional clothing, slang, songs and legends, related symbolism, and ceremonials.
Gadz'Arts activities are independent of the administration of the school and are exclusively run by the students and alumni, although the two parts often cooperate for organising cultural or sporting events.
