The term originated from a character in Medieval english literature, Reynard the fox, a trickster figure who
achieves his goals through cunning and wit.
In modern use, 'Reynard' describes a promiscuous,
guileful and opportunistic knave (male, as the female equivalent to a Reynard is known as a Vixen) who is usually found around the dancefloors of sportsbar at Mona Vale hotel or Soho in King's Cross.
Recently, sightings of this magnificent creature have been reported in Arq and Phoenix, cat dancing (it's signiture dance) to tribal house music.
