BITNET /bit'net/ [acronym Because It's Time NETwork] n.   Everybody's least favorite piece of the network (see {network,the}
).  The BITNET hosts are a collection of IBM dinosaurs and
   VAXen (the latter with lobotomized comm hardware) that communicate
   using 80-character EBCDIC card images (see {eighty-columnmind}
); thus, they tend to mangle the headers and text of
   third-party traffic from the rest of the ASCII/RFC-822 world with
   annoying regularity.  BITNET is also notorious as the apparent home
   of BIFF.
