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.
