flopping
n.— «Technique comes into play when clearing the bar, because you must turn your back to the bar while clearing it, a technique called flopping.» —“Library tech awarded three silver medals at National Track meet” by Derek B. Carlson in Parris Island, South Carolina Marine Corps News Sept. 12, 2006. (source: Double-Tongued Dictionary)
“Flopping” was popularized by Richard Fosbury, as explained by the International Olympic Committee.
This dates back to gold medalist Dick Fosbury in the 1968 Olympics. It was called the Fosbury Flop after his method of clearing the bar. I believe the term was first used by Medford, Oregon sportswriter.
You mean exactly like I mention in the previous comment?
