I have this little ball-like structure in between my buttocks that rolls around on the middle of the bottom portion of my sacrum. No pain. Feels bony.

In brief: Lipoma?

If it is freely mobile, it is probably a lipoma.
Unlikely to be bone. An xray would show that it is not bone. See a doc, probably easily diagnosed and then you can just ignore it.
