"Numa Numa" is an Internet meme based on a video by American vlogger Gary Brolsma made after the song "Dragostea Din Tei" as performed by Moldovan pop group O-Zone. Brolsma's video, entitled "Numa Numa Dance", was released on December 6, 2004, on the website Newgrounds under the username "Gman250" and shows Brolsma lip-syncing the song with lively gesticulations and dance moves. The video title is derived from the Romanian words "nu mă nu mă" that occur in the refrain of O-Zone's song. It was the first Numa Numa-themed video to gain widespread attention.
