Place it at the very start of a reaction edit as the introduction, then follow it with the Kiko Laugh so the roast gets a response beat, and finish with a shocked reaction sound for the other person's reply.
About this sound
A very short Spanish voice clip, about a second and a half, of a woman announcing 'soy yo, Cristina' before landing the insult 'pelotudo' right after her name. It feels cheeky, abrupt and deliberately rude, like a mock introduction that turns into a roast before the listener has time to react.
