spike

   <jargon> To defeat a selection mechanism by introducing a
   (sometimes temporary) device that forces a specific result.
   The word is used in several industries; telephone engineers
   refer to spiking a relay by inserting a pin to hold the relay
   in either the closed or open state, and railroaders refer to
   spiking a track switch so that it cannot be moved.  In
   programming environments it normally refers to a temporary
   change, usually for testing purposes (as opposed to a
   permanent change, which would be called hard-coded).

   peak in an otherwise rather constant graph (e.g. a sudden surge in line
   voltage, an unexpected short "high" on a logical line in a circuit).
   Hackers frequently use this for a sudden short increase in some quantity
   such as system load or network traffic.
