However, "cuco" is not a common English word. It has a few potential meanings depending on context:
* "Cuco" can refer to a type of bird, similar to a cuckoo. This is the most literal translation.
* "Cuco" can also be a slang term for a "bogeyman" or "ogre" in some regions of Spain. In this case, "Los cucos" might be understood as "the monsters" or "the scary things."
Without further context, it's difficult to give a precise English translation of "Los cucos." If you could provide more information about where you encountered this phrase, I might be able to provide a more specific translation.
