The line comes from A Justiceira de Olinda, the first episode of the Brazilian anthology series As Brasileiras. The phrase itself is typical Northeastern Brazilian slang, with homi as a colloquial form of homem, used here as a disgusted interjection. Clipped from the broadcast, the three-second outburst began circulating on Brazilian soundboards and WhatsApp groups as a reaction audio. It endures because the accent and blunt wording make it instantly recognizable, giving creators a short, expressive way to signal shock at something gross or absurd.
