rainbow around the sun
slingshot around the sun
When a New York City cab driver takes you to LaGuardia Airport by way of the Battery Park Underpass, circling around the financial district. It's a quick but needlessly long route. From the movie Star Trek IV, in which Captain Kirk slingshots the Enterprise around the sun to warp back in time.
Example:
"He did some kind of slingshot around the sun... took 2 minutes but added $10 to the fare! That's the last time I let anyone do that."
