rain dance: n. 1. Any ceremonial action taken to correct a
hardware problem, with the expectation that nothing will be
accomplished. This especially applies to reseating printed circuit
boards, reconnecting cables, etc. "I can't boot up the machine.
We'll have to wait for Greg to do his rain dance." 2. Any arcane
sequence of actions performed with computers or software in order to
achieve some goal; the term is usually restricted to rituals that
include both an incantation or two and physical activity or
motion. Compare magic, voodoo programming, black art, cargo
cult programming, wave a dead chicken; see also casting the
runes.
