The first thing to know about the Donald J. Trump dance craze is that it’s not really a craze. (Not yet, at least.) Nor, to be honest, is it a dance.

What is certain, however, is that the president-elect’s signature shimmy is currently en vogue with all manner of professional athletes, imitated by at least five National Football League players on Sunday, as well as by Jon Jones, the current heavyweight champion of the U.F.C., who seemingly helped spread the fad on Saturday night after knocking out Stipe Miocic in the third round.

Mr. Jones celebrated by rocking from hip to hip and pumping his fists at waist level — both hallmarks of Mr. Trump’s dancing — before pointing his finger at Mr. Trump, who was attending the fight in New York and sitting ringside. Mr. Trump, never one to pass up a compliment, beamed in the moment and soon reposted Mr. Jones’s performance on his Truth Social account.

The trend continued on Monday when Christian Pulisic of the U.S. men’s national soccer team celebrated a goal with his own version of the shimmy.

“Well obviously that’s the Trump dance,” Mr. Pulisic told reporters when asked about the celebration. “It was just a dance that everyone’s doing. He’s the one who created it. I just thought it was funny.”
