legalese
 n.

   Dense, pedantic verbiage in a language description, product
   specification, or interface standard; text that seems designed to
   obfuscate and requires a {language lawyer} to {parse} it. Though
   hackers are not afraid of high information density and complexity in
   language (indeed, they rather enjoy both), they share a deep and
   abiding loathing for legalese; they associate it with deception,
   {suit}s, and situations in which hackers generally get the short end
   of the stick.
