The word gritão means a loud shout in Portuguese, and susto means fright, so this clip is named for exactly what it delivers. It circulates widely on Brazilian soundboards, WhatsApp and TikTok as a quick scare effect, often shared without a clear original video or creator attached. Like the Vine Boom, it works because it is short, loud and instantly recognisable as a shock. Creators keep returning to it for pranks, horror edits and reaction clips, where a sudden scream needs no explanation and still startles an audience expecting something quieter.
