This one apparently coined by D. F. Wallace in Infinite Jest, p. 177:
Formication, n., the condition of being infested with ants, in usage typically of the hallucinatory variety. Did I experience yes some ~ in detox? I did. (ibid)
There are some truly wonderful words in the English language.
On an unrelated thought: Just got back from a very nice Passover seder at the house of some friends of the family. Nice people, good food, and a great deal of singing. I do not know nearly enough of the old folk melodies, mostly since I didn’t grow up in a kibbutz where these things were omnipresent.
High point of the evening: Had gadia, one of the standard songs for the evening, complete with an illustrative shadow puppet show. The puppet representations of God and the angel of death were quite interesting, and the sound effects (added by the audience) just made it all work.
