It could be described as key locations for an object or objects in an
animation. An object moves from point a to point b to point c which
would be your keyframes while the frames between would be the motion
frames between those points. You can set up any number of keyframes
to decribe motion between any number of locations or actions within
a scene.
Some animation software will allow you to specify keyframe locations
or actions and will interpolate the movement for you. This is a handy
feature especially in a GUI interface. All you have to do is point
and click the locations for each oject you wish to animate then define
movement paramaters such as speed, arcs, rotations, accelerations, etc
between your keyframe points and it will handle all of the tedious
math for you.

It's something only used in stupid animations with characters so stupid they
need to frame their key in order not to lose it.

As Ken described, keyframes allow you to specify a limited number of targets
within an animation, and have the rest of the frames interpolated or
"tweened" to create smooth movements. I guess the term goes back to
traditional cel animation, where the master artists would draw the major
positions of the characters, and these would be filled in by assistants.
In POV-Ray, you can use my Automatic Clock Modifier to specify a list of
keyframes and (optionally) transition methods, to interpolate between
floats, vectors, pigments, textures, etc. My Spline Macro File also allows
you to specify a list of 3D positions and have these interpolated in various
ways. You'll find both at http://www.geocities.com/ccolefax.
