Psychosprocket

Psychosprocket is an interesting word.  It seems that no search engine knows how to find psychosprocket, so I'm making psychosprocket a common theme of this post entitled "Psychosprocket" to see how long it takes for the search to filter.  It makes me ponder what a psychosprocket really is.  Is it a crazy guy with a few gears loose?  Or is it just a machine part that enables ludirous speed?  The mystery of the psychosprocket may forever be a mystery.
