Hey guys, Peter Griffin here, to explain the reference. You see, in 2017, there was a movie that released named “Coco”. One of the characters in this movie is named Máma Coco. This is the grandmother of the main character. In the post above, the user intentionally misspells “Coco” with “Koko” to make people think it is not a reference. I believe otherwise. This might not be an intentional reference, though.
