Norm is the Russian slang word for normal, and as a sound it circulates mainly as a short reaction clip for social video and messaging rather than as a line tied to a widely documented film, show or recording. Its appeal comes from its simplicity: one familiar word can signal that something is acceptable without praise or complaint. That makes it easy to reuse across different languages and contexts, especially in memes where a flat, unbothered response is funnier than an enthusiastic one. Creators keep returning to it because it fits almost any ordinary outcome.
