Filho da puta is a well known Brazilian Portuguese insult, literally meaning son of a bitch, and it is widely used online as a raw exclamation of anger, disbelief or frustration. As a short soundboard clip it circulates mainly in meme videos, livestreams and reaction edits, where the language itself is less important than the unmistakable tone of the shout. Its staying power comes from that versatility: it works for gaming fails, sports blunders, prank reveals and everyday annoyances, giving creators a punchy, culturally specific reaction that needs no translation to be understood.
