Ribs that are directly connected to bone on only one end are "floating". There are short ribs in humans that are bonded to the sternum via cartilage, so they are free to flex or "float" at one end. This provides for increased flexibility, and decreased stress on the spine.
Ribs 11 and 12 are known as floating ribs because they do not attach to the sternum like the other ribs do. Instead, they are only connected to the vertebrae in the back, giving them a floating or free-end appearance.
The eleventh and twelfth ribs only attach to the spine, and do not attach to the sternum.

They are called floating ribs because they are not attached to the sternum or any other anterior bone where as the other ribs are.
