   <jargon> (University of Waterloo) Some varieties of wide paper
   for printers have a perforation 8.5 inches from the left
   margin that allows the 3.5 inch excess on the right-hand side
   to be torn off when the print format is 80 columns or less
   wide.  If done with sufficient aplomb this makes a sound like
   the "woof" of a dog.  If the large part is the "woofer" then
   the small part must obviously be the "tweeter", following the
   names for the large and small cones in a hi-fi loudspeaker.

   These terms have been in use at Waterloo since 1972, but are
   unknown elsewhere.

   Compare {chad}.
