Blue Glue
[IBM] n. 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 pens. 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'.
