tourist n. 1. [ITS] A guest on the system, especially one who generally logs in over a network from a remote location for comm mode , email, games, and other trivial purposes. One step below luser. ITS hackers often used to spell this turist , perhaps by some sort of tenuous analogy with luser (this usage may also have expressed the ITS culture's penchant for six-letterisms, and/or been some sort of tribute to Alan Turing). Compare twink , lurker , read-only user. 2. [IRC] An IRC user who goes from channel to channel without saying anything; see channel hopping.
