In our insular part of Mid-Coast Maine, we used the term "jigaboo" for a scary entity in a ghost story.

"Nappy" as a term relating to cloth or fabric texture certainly makes sense to me, as it would to anyone who has worked with fabric.

Any just why some people with straight hair envy or abhor those with curly or wavy hair, and why others with curly or wavy hair envy abhor those with straight hair is a mystery.

It's a minefield for the innocent, and evidently for the less than innocent!
