Hastad built a following in Brazil as a Twitch streamer playing shooters, where his loud, high-pitched reactions became as recognisable as his gameplay. Short clips of those moments, nicknamed gritinhos in Portuguese, began circulating separately from the streams on social media and soundboards. Fans started using this scream out of context as a universal sign of panic or tilted rage. Its short length and unmistakable pitch helped it survive beyond the original broadcasts, becoming a staple reaction sound for Brazilian gaming edits and memes.
