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.
