pacochi is incorrectly written, and should be written as "Pacochis" as meaning:
The correct term is Pacochis and it is indeed a dance typical of the Region of San Pedro of Achacachi, in Bolivia. They are as in Colombia the Macheteros in the coffee area, but they are dancers dressed as or with masks and blonde wigs. They have many bells in his disguise and used machetes or large knives. Also you could say them Matachines.
