The Superderby (superclásico) is the most important football rivalry in Argentina, and the most important local derby. It is contested between Buenos Aires rivals Boca Juniors and River Plate. It derives from the Spanish usage of "clásico" to mean derby and the prefix super is used because Boca Juniors and River Plate are the two most popular and successful teams in Argentine football comendering more than 70% of all Argentine football fans between them.
The Superderby is known worldwide as one of world football's fiercest and most important derbies. It is particularly noted for the passion of the fans, the stands of both teams feature fireworks, coloured confetti, flags and rolls of paper. Both sets of supporters sing passionate songs (often based on popular Argentine rock band tunes) against their rivals, and the stadiums are known to bounce with the simultaneous jumping of the fans. Sometimes the games have been known to end in riots between the hardest supporters of both sides or against the police. The English newspaper The Observer put the Superclásico at the top of their list of 50 sporting things you must do before you die.
