“Fork in the road” is a term, but what about “spoon in the road”? “Was walking, came to a fork in the road, and took the one less traveled. Then I came to a spoon in the road, and called it a cul-de-sac” was posted on Twitter on June 2, 2010. “So, how come a cul-de-sac isn’t called a spoon in the road?” was posted on Twitter on August 23, 2011.
     
“If a place where the road splits is a “fork in the road”, would a cul-de-sac be a spoon in the road?” was posted on Reddit—Shower Thoughts on July 12, 2014. “There’s a fork in the road. A spoon in the road could be a cul-de-sac. So, a spork in the road is a roundabout” was posted on Twitter on March 21, 2017.
       
“Building cul-de-sacs is a dead end job” and “I live on a cul-de-sac, which is French for ‘Everybody here is white‘“ are other cul-de-sac sayings.
         
   
Wikipedia: Dead end (street)
A dead end, also known as a cul-de-sac (/ˈkʌldəsæk, ˈkʊl-/, from French for ‘bag-bottom’ ), no through road or no exit road, is a street with only one inlet or outlet.
 
The term “dead end” is understood in all varieties of English, but the official terminology and traffic signs include many different alternatives. Some of these are used only regionally. In the United States and other countries, cul-de-sac is often not an exact synonym for dead end and refers to dead ends with a circular end, allowing for easy turning at the end of the road. In Australia and Canada, they are usually referred to as a court when they have a bulbous end.

So, there are “forks” in the road. Is a cul de sac considered a “spoon” in the road?

If a place where the road splits is a “fork in the road”, would a cul-de-sac be a spoon in the road?

There’s a fork in the road. A spoon in the road could be a cul-de-sac. So, a spork in the road is a roundabout.
