Dragostea Din Tei was released by the Moldovan pop group O-Zone in 2003 and became a huge hit across Europe the following year. Its Romanian chorus went viral online through the Numa Numa dance video, in which a young man lip-synced and danced enthusiastically to the song at his computer. That clip helped make the track one of the first truly global internet memes. Years later, the chorus still appears in short videos, remixes and nostalgic edits because the melody is instantly recognisable even to people who never learned the lyrics.
