As you'll notice from my post count I'm a newbie too, but I've been lurking awhile and from what I've figured, people 'bump' up a thread that has become buried by the many other threads so it will appear at the top of the thread list again. (Don't know about you, but I generally limit myself to the newest threads as there are just too many to keep track of otherwise.) By "bumping" up a thread, it gets noticed by more people and they can get more information or suggestions. That's my take on it. If a thread has been moved, I believe it will actually say "moved" and generally will tell you where it has been moved to. Hopefully, If I'm wrong, someone else will have better information for you.
