Blue Glue

Blue Glue n.  [IBM] IBM's SNA (Systems Network
   Architecture), an incredibly {losing} and {bletcherous}
   communications protocol widely favored at commercial shops that
   don't know any better.  The official IBM definition is "that which
   binds blue boxes together."  See {fear and loathing}.  It may
   not be irrelevant that {Blue Glue} is the trade name of a 3M
   product that is commonly used to hold down the carpet squares to
   the removable panel floors common in {dinosaur pen}s.  A
   correspondent at U. Minn. reports that the CS department there has
   about 80 bottles of the stuff hanging about, so they often refer to
   any messy work to be done as `using the blue glue'.
