About this sound
Nathalia Kassino's distinctive laugh from Bando do BK, a short contagious giggle Brazilians use as a reaction in memes, edits and funny chats.
The clip is six seconds of Nathalia Kassino laughing out loud, starting with a sharp burst and rolling into a breathy, uneven giggle that keeps climbing. It is not a polite chuckle, it sounds spontaneous and a little uncontrollable, which is why it lands so well as a reaction. Played over a fail, an awkward confession or a joke that went too far, it tells the viewer exactly how to feel without any words. The laugh is infectious on its own, but timed right it also makes the moment on screen feel much funnier.
