i forgot to mention, a lot of the words came from James Ellory's LA Quartet (1 and 2), and his Underworld USA Trilogy.
The other chunk came from an Android app called Orphic, which has a bunch of esoteric words; me perusing Dictionary.com for words, and favorite'ing them; and a hilariously-over-the-top Audiobook called WORDSMART: GENIUS EDITION, which geniuosly doesn't include the PDF, so someone in the Amazon comments ended up transcribing and putting up: https://pastebin.com/iCw9P5ix
