The exact origin of Ni Idea Loco is not documented, so the clip is best known through its circulation as a short reaction sound on soundboards and in edited videos. The Spanish phrase is widely understood as a casual way to admit you do not know, which helped it travel beyond Spanish speaking audiences as a universal shrug. Creators reuse it for quiz fails, confused characters and everyday moments where an honest answer would be less funny than a laid back admission of cluelessness.
