Shakira doing the tongue thing should be a meme in 5…4….3….2….

The 43-year-old Colombian and Lebanese singer opened the halftime show with a medley of her hits, including "She Wolf" and "Wherever, Whenever." After she finished, she leaned into the camera and wiggled her tongue at the camera.

Shakira and Jennifer Lopez’s halftime show at the 2020 Super Bowl fueled the internet with new memes—and gave some people a culture lesson.

Shakira was performing her most iconic song, “Hips Don’t Lie,” when she released a high-pitch trill and rapidly moved her tongue. The moment was immediately captured and shared on Twitter, where people were live-tweeting the game.

Chiming in because I know everyone will be making jokes about this for days — this is a popular Arab tradition, called zaghrouta, used to express joy at celebrations. In the melting pot that is Miami, you could not have picked a better Super Bowl act and this was a lovely touch. https://t.co/q1H9l8UpQ5
