The exact original clip behind Cuy Cuy Cuy is not widely documented, but the phrase itself points to the Spanish word for guinea pig, and the sound has circulated as a short, shareable meme clip rather than as part of a well-known film, song or television show. Online, it is mainly passed around through soundboards and short-form videos, where its short length and instantly recognisable repetition make it easy to reuse. That simplicity is also why it has stayed in rotation: creators can drop it into almost any light, funny moment without needing viewers to know a backstory.
