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.
