Mario is Nintendo's famous Italian plumber and the star of the Super Mario games, where his cheerful voice lines became as recognisable as his red cap and moustache. Mamma Mia is one of his best-known exclamations, used in games when he reacts with surprise, delight or alarm, and fans have lifted short voice clips like this one for reaction videos, streams and meme edits. Because the character is known worldwide and the line needs no translation, it still works instantly in short-form content, signalling playful shock in a way viewers understand even without context.
