Undecided, middle-of-road voters called 'mug wumps' in late 19th century

[Codeine]

4. Interesting. I've only encountered the word

in the writings of William S. Burroughs.

“ These creatures secrete an addicting fluid from their erect penises which prolongs life by slowing metabolism. . . . Addicts of Mugwump fluid are known as Reptiles. A number of these flow over chairs with their flexible bones and black-pink flesh. A fan of green cartilage covered with hollow, erectile hairs through which the Reptiles absorb the fluid sprouts from behind each ear. The fans, which move from time to time touched by invisible currents, serve also some form of communication known only to the Reptiles.”
