Fandangoing refers to the viral sensation that began in April 2013 following WWE’s WrestleMania 29. After Fandango's debut, the crowd at Monday Night Raw began humming his ballroom-style entrance theme, 'ChaChaLaLa,' while performing a rhythmic swaying dance. The phenomenon quickly spread beyond the wrestling ring, with sports teams, news anchors, and celebrities joining in on the dance. In the meme world, it is used to represent sudden outbursts of rhythmic energy, infectious trends, or simply to mock the absurdity of viral fame. While the hype eventually cooled, the meme remains a nostalgic touchstone for the 'Post-Mania' crowd energy that defined a specific era of WWE history.
