The phrase ai que susto is everyday Brazilian Portuguese for oh, what a scare, and this version became a shareable reaction clip because of the little girl's dramatic delivery. Online, it circulates in Portuguese-speaking meme edits, prank compilations and short videos where someone is frightened by something small. Its mix of shock, religious exclamations and mild swearing captures a very Brazilian style of overreacting, which is why creators keep reusing it as a punchline for startled moments instead of recording their own scream.
