psyton
     
         /si:'ton/ (From {TMRC}) The elementary particle
        carrying the sinister force.  The probability of a process
        losing is proportional to the number of psytons falling on it.
        Psytons are generated by observers, which is why demos are
        more likely to fail when lots of people are watching.  This
        term appears to have been largely superseded by {bogon}; see
        also {quantum bogodynamics}.
