Mauro Ranallo is a Canadian combat sports and wrestling commentator known for his passionate calls in WWE, boxing and MMA, and Mamma Mia became his best known catchphrase. Borrowed from the classic Italian expression of surprise, his delivery turned it into a signal for a match changing moment. Clips of his calls were shared widely by wrestling and boxing fans online, then cut into short soundboard and meme edits. It remains popular because that one phrase instantly imports big fight energy into any video.
