Online, meu neguinho spread through WhatsApp groups, meme pages and soundboards because the line works without any context and can be understood from the tone alone. Brazilian creators keep reusing it for greetings, entrances and ironic introductions, especially when someone wants to sound confident, friendly or exaggeratedly cool in just a few seconds of audio.
