jack in: v. To log on to a machine or connect to a network or
BBS, esp. 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.
