understeer means the front tires are slipping more than the rears.
oversteer means the rear tires are slipping more than the fronts.
neutral would be if your steering input was just enough to follow the
arc of the turning radius.
understeer is considered a "safer" condition for most drivers since it is
a stable condition - you initiate your turn by steering toward the center
of the arc, the fronts start to slide, you dial in some more steering
toward the center of the arc, etc.
oversteer is an unstable condition - you initiate your turn by steering toward
the center of the arc, the rears start to slide, you counteract by steering
away from the center of the arc until the steady state is reached, but not
too far or you will initiate a new turn in the opposite direction and not too
late or you have already spun.
the advantage to oversteer is that you are better set up to apply power
upon exiting the turn. plus it feels great =8)

in general, RWD's tend to (or can be induced to) oversteer while FWD's are
primarily understeer.
this is an oversimplification since this feature can be affected by weight
distribution, engine power (and it's distribution in AWD/4WD), weight transfer,
suspension setup, coefficients of friction at the contact patches, steering
input, etc.

I found this stuff on oversteer and understeer.
