The recent World of Warcraft: Battle for Azeroth PTR 8.1.5 (build 29352) introduced the Kul Tiran and Zandalari dance animations.
The male Kul Tiran dance resembles the Mr. Thiccman meme. The female Kul Tiran has two ballet dancing moves, but the way it is stylized, seems inspired from a cartoon or Disney animated film.
The female Zandalari has moves from the South African Gwara Gwara dance. The Gwara Gwara dance became viral when Dj Bongz invited fans to a Gwara Gwara dance challenge that had them share online videos of themselves dancing like him.
Gwara Gwara was made popular in USA by Rihanna during the Grammys 2018. Chris Brown also jumped on the dance craze during his concert in South Africa.
