Snap oversteer

First of all, I am sorry if this is the wrong place for this but I figured this phenomenon would differ between vehicles so here's my question...
I have heard of many people speak of something called snap oversteer. I know what oversteer is, but what is snap oversteer?

Snap oversteer is just sudden oversteer. Depending on your tires and suspension setup a car can have the tendency to oversteer sharply without warning. This is something that is sometimes characterized with mid-rear and rear-engine vehicles if not tuned properly.

Thanks a lot man. That's what I was thinking but I wasn't sure if it was more complicated than that.
