YMCA was released in 1978 by the American disco group Village People and became one of the defining hits of the disco era. The song took on a second life in sports stadiums, especially in American baseball, where fans perform the letter dance during breaks in play alongside crowd cheering. That stadium tradition, plus its use at weddings, school discos and pride celebrations, kept the chorus in circulation for decades. Online, the short chorus loop is shared as a reaction to group celebrations, team wins and any moment calling for a coordinated dance break.
