Dollars Pictures

In Peru, a nickname for the U.S. dollar is "coco", which is a pet name for Jorge ("George" in Spanish), a reference to the portrait of George Washington on the $1 note.
Puerto Ricans, both living in Puerto Rico and in the United States, may refer to the dollar as "peso".
In some places in Mexico, prices in U.S. dollars are referred to as "en americano" ("in American"), with the word "peso" used in Mexico primarily to refer to the Mexican peso.
Cubans call the U.S. dollar "fula". Loosely translated from cuban jargon mean bad or not good. American money was not bad to have or use by cubans in the island, but it's posession was penalized before the mid-90's, hence the nickname.
