psyton: /si'ton/ n. [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largely superseded by {bogon}; see also {quantum bogodynamics}.
