Scrapie
The name scrapie is derived from one of the clinical signs of the condition, wherein affected animals will compulsively scrape off their fleeces against rocks, trees, or fences. The disease apparently causes an itching sensation in the animals. Other clinical signs include excessive lip smacking, altered gaits, and convulsive collapse.
Scrunchie
The Scrunchie was invented by Philips E. Meyers in 1963 but was not patented until 1987 by Ronny Revson, who named the decorative hair accessory the Scunci after her pet toy poodle. The name Scrunchie was a natural evolution, because the fabric scrunched up. After patenting the Scrunchie, Revson spent most of her time in legal disputes, both with manufacturers and her own lawyers. Scrunchies were particularly popular in the 1980s and 1990s, including larger, more elaborate versions. Scrunchies regained popularity in the mid 2010s. Debbie Gibson in particular wore them; Madonna wore a large velvet scrunchie in "Desperately Seeking Susan". An episode of "Sex and the City" mocked the fashion.
