Bana ne is everyday Turkish slang for none of my business, and amk is a coarse intensifier that makes the dismissal deliberately rude, so the full phrase is much blunter than a polite brush-off. The exact recording behind this clip is not tied to a known film, show or public figure in the available information, and it circulates mainly as a short user-shared reaction sound. That anonymity has helped it spread, because creators can drop it into any argument, gossip clip or overreaction without needing the original context, and its attitude still lands immediately.
