The gritinho comes from Big Enough, a 2017 song by Australian musician Kirin J Callinan featuring a famous sustained scream by Jimmy Barnes. Its video placed a giant screaming cowboy in the sky, and that image and yell were clipped, reposted and remixed across meme pages. In Brazil the moment picked up the name gritinho, meaning little scream, and this second version circulates as a ready to use edit sound. It stays popular because the scream instantly signals something impossibly big arriving.
