jack in
To log on to a machine or connect to a network or BBS, especially for purposes
of entering a virtual reality simulation such as a MUD or IRC (leaving is
"jacking out"). This term derives from cyberpunk SF, in which it was used for
the act of plugging an electrode set into neural sockets in order to interface
the brain directly to a virtual reality. It is primarily used by MUD and IRC
fans and younger hackers on BBS systems.
