Moments after Shakira's performance alongside Jennifer Lopez at the Super Bowl halftime show, memes surrounding one moment from the "Waka Waka" singer's performance immediately went viral.

At a memorable point during the show, the 43-year-old Colombian artist looked straight at the camera and wiggled her tongue while making a sound. While this gesture left some fans puzzled, Shakira was actually nodding at her Lebanese heritage.

If I ain’t seen anything ever that’s more meme-worthy, I give you Shakira tongue lol pic.twitter.com/6HcOGBa7Mx — Neek✊🏽 (@Sarcastic_Asset) February 3, 2020

The "tongue-wag" is called a zaghrouta, or ululation in English. It is a long, wavering, high-pitched vocal sound accompanied by a rapid back and forth movement of the tongue. It's used by women in Middle Eastern and North African cultures to express joy and strong emotions. Zaghrouta is often used during Arabic weddings to celebrate the union between two people, at parties and sometimes at funerals to honor a person's life.

You really have to understand how huge Shakira’s performance was for the Middle Eastern community. She had belly dancing, a mijwiz and a derbeke, performed “Ojos Asi” which was one of the few Shakira songs to have Arabic in it, did a Zaghrouta, all love on the biggest stage — Danny Hajjar داني حجار 🇱🇧 (@DanielGHajjar) February 3, 2020

Though she was born and raised in Barranquilla, Colombia, Shakira's paternal grandparents are from Lebanon, a country she has always kept close to her heart. As a matter of fact, the Grammy Award-winning singer's last name is Mebarak, a common name in the Arab world. She often incorporates her heritage and culture in her art and music — through her belly dancing moves, for instance, or her use of sounds in songs such as "Eyes Like Yours."
