The phrase comes from the 1991 Super Mario World animated television episode “Mama Luigi,” in which Luigi tells Yoshi a story about how they met. The episode’s exaggerated dialogue and animation later became popular material for YouTube Poop remixes and other early video memes. “Mama Luigi” remained recognizable because it combines a familiar Nintendo character with an unusually silly nickname and distinctive delivery. It continues to appear in gaming edits, cartoon nostalgia posts, remix videos, and jokes about Luigi acting like a parent.
