Simone Biles made history during qualifications at the World Gymnastics Championships by landing a Yurchenko double pike on vault.
Because she is the first woman to do so in international competition, the skill is now named the "Biles II." It's the fifth skill named after her and the second on vault.
That may seem like a lot of skills, but it's not the most in women's gymnastics history. Nellie Kim, who competed for the Soviet Union at the 1976 and 1980 Olympics, has seven elements named for her in the code of points.
To get a skill named after a gymnast, they must submit the skill to the International Gymnastics Federation prior to competition at an international event, such as the Olympics or World Championships. The gymnast must be the first to successfully compete the skill without major error. Should the gymnast do so, the code of points will rename the element by the gymnast's last name.
