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.
Maakies
Millionaire has given differing accounts of the origin and meaning of the word "maakies." "Maak" is the name of a character in the strip, a ship's captain who apparently is Uncle Gabby's employer, and in one sense the strip seems to be named after him. Discussing the strip's development, Millionaire said "I fleshed them [the characters] out as best I could at the time, knowing that they'd grow over time. That's why I didn't call the strip Drinky Crow. I called it Maakies because I didn't know who would become the most important character as I went along."
