ken

ken /ken/ n.  1. [UNIX] Ken Thompson, principal inventor
   of UNIX.  In the early days he used to hand-cut distribution
   tapes, often with a note that read "Love, ken".  Old-timers still
   use his first name (sometimes uncapitalized, because it's a login
   name and mail address) in third-person reference; it is widely
   understood (on Usenet, in particular) that without a last name
   `Ken' refers only to Ken Thompson.  Similarly, Dennis without last
   name means Dennis Ritchie (and he is often known as dmr).  See
   also {demigod}, {{UNIX}}.  2. A flaming user.  This was
   originated by the Software Support group at Symbolics because the
   two greatest flamers in the user community were both named Ken.
