Filha da mãe is a common Brazilian Portuguese expression of annoyance, roughly equivalent to calling someone a son of a bitch, and this clip circulates online as a short reaction meme rather than as a line tied to a specific film or television show. Shared in Portuguese-language meme communities and soundboards, it is recognised instantly by Brazilian viewers for its tone of disbelief and irritation. Its continued use comes from that familiarity: creators can signal frustration in one short burst, add local flavour to a fail or prank, and rely on an expression that needs no setup to land.
