The phrase is Brazilian Portuguese slang, roughly meaning look at that angry guy, with ixi acting like a startled whoa and puto meaning furious in this context. The clip spread as a short reaction sound on Brazilian meme pages, WhatsApp groups and short video edits, where a shouted caption style line is often pasted over fights, arguments and meltdowns. Its appeal is the casual narration, as if a friend is commentating live, which made it reusable far beyond any single original video or moment online today.
