    Well, the Lindy Line is a dance step!  Somebody has a sense of humor!
    
    LINDY: Line dance move, 8-count series pf side shuffles and rock steps
    EXAMPLE:
    1&2     Side step right & step left beside right, side step right
    3-4     Rock step left slightly behind right, recover weight to right
    5&6     Side step left & step right beside left, side step left
    7-8     Rock step right slightly behind left, recover weight to left

    Composite lines are a bit more legit: they are a combination of great
    circles and parallels.  Here is an example:
    
    If you were to sail a great-circle course from Seattle Washington to
    Yokohama the course would cross the Aleutian islands, so the procedure
    would be to sail the great-circle to a maximum safe latitude, sail
    directly West until you meet the great-circle again, and then continue
    following the great-circle to the great-circle destination point off
    the coast of Japan. This procedure is known as composite sailing.
