The exact origin of the Requiem Da clip is unclear, and it circulates mainly as a short soundboard upload shared between editors. Its appeal comes from the requiem style itself, long associated with masses for the dead and dramatic classical scoring, which gives even a five second excerpt an instantly solemn weight. Online, creators borrow that weight for comedy, posting the sound under fails, eliminations and exaggerated goodbyes. That shared shorthand keeps it in use, because audiences understand the mock mourning without needing any context or explanation before the punchline lands.
