The Coco or Coca (also known as the Cucuy, Cuco, Cuca, Cucu, Cucuí or El-Cucuí) is a mythical ghost-like monster, equivalent to the bogeyman, found in many Hispanophone and Lusophone countries. It can also be considered an Iberian version of a bugbear as it is a commonly used figure of speech representing an irrational or exaggerated fear. The Cucuy is a male being while Cuca is a female version of the mythical monster. The "monster" will come to the house of disobedient children and make them "disappear". Names and etymology The myth of the Coco, or Cucuy, originated in northern Portugal and Galicia. According to the Real Academia Española, the word coco derives from the Galician and Portuguese côco , which means "coconut". The word coco is used in colloquial speech to refer to the human head in Spanish. Coco also means "skull". The word cocuruto in Portuguese means "the crown of the head" or "the highest place" and with the same etymology in Galicia, crouca means "head", from proto-Celtic *krowkā-, with variant cróca; and either coco or cuca means "head" in both Portuguese and Galician. It is cognate with Cornish crogen, meaning "skull", and Breton krogen ar penn, also meaning "skull". In Irish, clocan means "skull". Many Latin American countries refer to the monster as el Cuco. In northern New Mexico and southern Colorado, where there is a large Hispanic population, it is referred to by its anglicized name, "the Coco Man". In Brazilian folklore, the monster is referred to as Cuca and pictured as a female humanoid alligator, derived from the Portuguese coca, a dragon. Legend In Spain, Portugal, and Latin America, parents sometimes invoke the Coco or Cuca as a way of discouraging their children from misbehaving; they sing lullabies or tell rhymes warning their children that if they don't obey their parents, el Coco will come and get them and then eat them. It is not the way the Coco looks but what it does that scares most. It is a child eater and a kidnapper; it may immediately devour the child, leaving no trace, or it may spirit the child away to a place of no return, but it only does this to disobedient children. It is on the lookout for children's misbehavior from the rooftops; it takes the shape of any dark shadow and stays watching. It represents the opposite of the guardian angel
