Escrache is the name given in Argentina, Paraguay, Uruguay and Spain to a type of demonstration in which a group of activists go to the homes or workplaces of those whom they want to condemn and publicly humiliate in order to influence decision makers and governments into a certain course of action. This term was born in Argentina in 1995 and has since spread to other Spanish-speaking countries.
In Chile these actions are known as funa. In Peru they are known as roche and are often signed "El roche".
The word was coined for political usage in 1995 by the human rights group HIJOS, to condemn the genocides committed by members of the PROCESO who were pardoned by Carlos Menem.
By 2013, the term was in wide use in Spain, to define the direct action protests of the Plataforma de Afectados por la Hipoteca.
