Fresh Air Refreshes Totally (F.A.R.T.) was a fringe movement of wizards who preferred to wear robes at all times in public, even when in the vicinity of Muggles, because they believed that trousers "stem[med] the magical flow at source" and that having a "healthy breeze" around one's "privates" was desirable. The movement's president was Archie Aymslowe.
Members of the F.A.R.T. movement were repeatedly warned and fined for violating the International Statute of Wizarding Secrecy. The Statute laid out a code of dress that wizards and witches were supposed to follow when interacting with Muggles.
Muggles who encountered members of the F.A.R.T. movement apparently assumed they belonged to a cult.
The movement's acronym, F.A.R.T., is clearly a play on the English vulgarism fart, an informal term referring to flatulence. The full form itself appears to be a play on the term.
