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.
