Pichação
Pichação, sometimes misspelt as pixação, is the name given to graffiti in the Southeastern metropolises of São Paulo and Rio de Janeiro, in Brazil. It consists of tagging done in a distinctive, cryptic style, mainly on walls and vacant buildings. Many pichadores (pichação painters) compete to paint in high and inaccessible places, using such techniques as free climbing and abseiling to reach the locations.
