Roz Chast in the August 15 & 22 New Yorker:
As Mark Liberman observed in his recent LLog discussion of Satan sandwich in the political news, Satan here is a shit-avoidance term, with demonic overtones as a bonus. Chast has taken this and run with it.
In connection with the state fair food-on-a-stick theme, note Satan-on-a-stick among the offerings. There’s also a Satanburger, with the common libfix -burger; along these lines, Chast could have included a Satan dog (a hot dog wrapped in Satan) on the board.
