|(jargon)||J. Random Hacker - /J rand'm hak'r/ MIT jargon for a mythical figure;

This may originally have been inspired by "J. Fred Muggs", a show-biz chimpanzee whose name was a household word back in the early days of TMRC, and was probably influenced by J. Presper Eckert (one of the co-inventors of the electronic computer).
