The phrase Ma che ho fatto literally means but what have I done in Italian, and as a sound it has circulated mainly as a short reaction clip rather than as a line tied to one widely documented scene. Its appeal comes from how easily it translates across languages: the tone alone signals regret, panic and comic self-blame. Creators reuse it in fail videos, gaming clips and everyday mishaps, where a brief spoken reaction can summarise an entire accident. That simplicity keeps it useful long after its first viral uses.
