Noun (naval terminology): the universally supreme naval rank, awarded historically only to one seaman (Christopher Columbus) jointly by HRM Ferdinand and HRM Isabella of Spain, in recognition of his achievement in successfully navigating the Atlantic Ocean westward and (presumed at the time) the discovery of a shorter, less hazardous, and less expensive trading route to India from Europe.
"Upon his return from his first voyage to America, Christopher Columbus received the rank and title of "Admiral of the Ocean Sea" from Ferdinand and Isabella,
which rank he holds in perpetuity."

A totally arbitrary title given to Christopher Columbus for sailing to the Americas. Can be used to refer to any flashy title that has no actual meaning.
A PhD in liberal arts might as well be renamed "Admiral of the Ocean Sea".
