Historically the word "TAPATIO," is used to refer to dancing water. Historian Mendez Moreno states the word originates from the Indian tribe Coca Talapatioti, which in that language has two meanings; shooting water such as spring, or water with hills such as a water fall. Another historian, Francisco Javier Aceves, states that the word is derived from the Azteca Thapatioti Indian tribe. In their language, Tapatio was the unit of money used in the Aztec territories before the Spanish conquest and consisted of a small bag of 10 grams of cocoa seeds.
