Torcidas organizadas are formal associations of football fans in Brazil in the same vein as barras bravas in the rest of Latin America, hooligan firms in United Kingdom and ultras in the rest of Europe, North America, Asia, Australia and North Africa.

Barra brava is the name of organized supporters' groups of football teams in Latin America, analogous to European ultras and British hooligans in providing fanatical support to their clubs in stadiums and provoking violence against rival fans as well as against the police.
Members of barras bravas are scattered between the flags that they deploy. In the picture, barra brava of Club Atlético Nueva Chicago, from Argentina, in the middle of the crowd.
'Reception' is the name that football fans from some countries give to the choreography that the crowds exhibit in the stadiums for welcoming their teams when they go out to the pitch. In the picture, fans of Club Atlético Banfield, from Argentina, displaying a giant flag a few minutes before a match.
The Barras brava section of the stadium is recognizable for their flags, a characteristic unrivaled by other areas of the stadium has more quantity or density of such. In the picture, La Banda de Fierro is an organized supporter group of Gimnasia y Esgrima La Plata.
