The phrases are Italian for I will not pass and you will not pass, which explains why the clip travels so well as a reaction sound even outside Italian speaking audiences.

Online, creators reuse the repetition as a shorthand for guarding a doorway, defending a position or refusing a request, pairing the stern delivery with low stakes situations for comic contrast.
