Mama Coco is the great-grandmother at the heart of Pixar's Coco, a character closely tied to memory, music and family, which is why short clips using her name travel so well online. The phrase has circulated in meme edits and tribute videos, where the simple act of waking her becomes shorthand for reaching someone from an older generation. It stays in use because the reference is warm, instantly recognisable and works in both funny and emotional edits without needing much explanation.
