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.
Paki (slur)
Spike Milligan, who was white, played the lead role of Kevin O'Grady in the 1969 BBC sitcom "Curry and Chips". O'Grady, half-Irish and half-Pakistani, was taunted with the name "Paki-Paddy"; the show intended to mock bigotry. Following complaints, the BBC edited out use of the word in repeats of the 1980s sitcom "Only Fools and Horses". Columnists have perceived this as a way of obscuring the historical truth that the use of such words was commonplace at the time. The word was used in "Rita, Sue and Bob Too" - set in Bradford, one of the first cities to have a large Pakistani community - and also in "East is East" - in which it is used by the mixed-race family as well as by racist characters. In the 2018 biopic "Bohemian Rhapsody", Freddie Mercury, who was Indian Parsi, is often addressed derogatorily as a "Paki".
