The sound comes from Nacho Libre, the 2006 comedy starring Jack Black as Ignacio, a monastery cook who secretly wrestles as a luchador. Ana de la Reguera plays Sister Encarnacion, the nun he admires from afar, and his exaggerated way of saying her name became one of the film's remembered running gags. Clips of the stretched call later circulated on soundboards and in short video edits, where it is reused whenever an entrance or a crush needs an overblown, sincere reaction.
