WHAT does 'body only' mean?

Does it just mean the outer camera with nothing inside or something? :/

If I buy a body only nikon d3000, is it still the normal camera?

Probably means no lenses. No flash and no accessories!

No lenses.

When someone is selling a camera like that Body only means that you are buying only the body of a camera without a lens. Typically comes with a batter and charger, maybe a manual. When you get into the world of digital SLR or even film SLR cameras with interchangable lens, they sell the lenses and bodies separately, so that when the next best thing comes out you don't have to buy a whole new setup, you just have to change the body to a different one.

Body only means you get camera with no lens. Fine if you have lenses. If not, you will eventually have to buy a lens.

It is the camera only, no lense.
