blame the flu!
Correction:
I would say in general "Vignetting" is dodging
in such a way that results in printing in an oval or
circular shape; there are many variations so dont get too
hung up on the shape.

However, vignetting is generally done in the reverse of
the images described, that is, the image is cropped in an
oval or circle with the outer part white. Burning in the
corners is also common since the eye tends to focus more
on the center of the image when the center of interst is
the brightest part of the image.

I wrote this when I came home from work, something I
should never do. Vignetting is done not only in the enlarger
or contact printer but also in the camera. When done in the
camera the result is as described: the subject is surrounded
by black. There are a great many variations to vignetting in
the camera. For instance one can use a translucent
vignetting mask to get a gray surround rather than black.
The edges of the vignetter control the hardness or softness
of the mask just as in enlarging, serrated edges producing a
softer effect. The distance from the lens to the mask also
affects the definition of the vignetting.
The same sort of attachment intended to hold diffusers
can be used for vignetting and many such attachments were
marketed over the years. On motion picture cameras these
devices are often called matte boxes and can be quite
elaborate. Usually the attachments for still cameras were
simpler but but quite elaborate ones were sold.
