Per The Daring Dufas:
Doesn't something like that happen to sailors? I seem to recall
something about the old time sailors spending a lot of time at sea on a
long voyage in the small ships having a problem when they came home to
dry land. Sea legs? The sailor becomes accustom to the motion of the
ship and perceives motion on land. ^_^

Now that you have mentioned it, I remember something like that after a
few hours on skates at a roller rink. Take the skates off, and there's
an adjustment period before you get your legs working right.
