Place it at the end of a short skit, right after the phone rings or the request for money appears, so it acts as the payoff. Follow it with a buzzer for a failed request, or lead into it with a baby laugh to soften the mockery before the dismissal.
About this sound
This is a short Portuguese voice meme built around the line about a poor person calling, delivered in a loud, blown-out style that makes the dismissal sound even more over the top. It feels snobbish, chaotic and deliberately rude in a playful way, landing as a joke about ignoring an unwanted call rather than a serious insult. The exaggerated delivery is what turns a simple complaint into a shareable punchline.
