Does "sea legs" mean being immune to seasickness or the feeling you get when you walk off a ship onto dry land and it still feels like you're rocking?

"Sea legs" originally meant the ability to maintain one's balance on a pitching deck solely by shifting one's weight from one foot to the other, without having to hold on to something solid to maintain balance. By extension this has come to include the ability to tolerate a rocking ship without getting seasick. When you come off a ship and still feel like you're rocking, you are experiencing "dock rock," which is also known by the scientific name "Mal de Debarquement Syndrome" (MDD or MdDS).
