Probably coined from the French word »coiffure«, the quiff is a mildly ridiculous though harmless hairstyle.
The quiff is characterised by a pointy greasy lump of hair at the front. It may be accompanied by silly shoes.
The dwindling of their natural habitats (roller discos, Eddie Cochrane gigs, etc.) means that quiff wearers are now an endangered species. See also mullet.
