The phrase is everyday French rather than a quoted line from a known film or show, and its humour comes from how ordinary it sounds. Voila marks the moment something is presented or revealed, and c'est super dur states plainly that it is really hard, so creators use the pairing as an instant caption in sound form. It has circulated on user soundboards as a short reaction clip, shared for gaming fails, schoolwork struggles, sports attempts and any video where effort meets an unexpectedly tough obstacle.
