The phrase nunca lhe vi translates from Portuguese as I never saw you, and as a standalone sound it circulates mainly as a short reaction clip rather than as a documented meme with a single famous source. Its appeal online comes from its simplicity: a five-second denial that needs no context to be understood by Portuguese-speaking viewers and is easy to recognise even by others from its tone. Because it is brief and instantly quotable, creators reuse it in reaction videos, short edits and meme compilations whenever a scene calls for feigned ignorance or a sudden refusal to acknowledge someone.
