The clip comes from Brazilian YouTuber Inutilismo in his video titled Um Filho Irritante, where the line appears around the five minute forty one second mark. Inutilismo built a large Portuguese speaking audience on YouTube with exaggerated reactions and everyday rants, and short excerpts like this were pulled into soundboards and meme edits. Because mas que merda is a common frustrated expression in Brazil, the shout travels easily beyond the original video and gets reused whenever creators need a quick, recognisable outburst in Portuguese.

Inutilismo shouting mas que merda in Portuguese, a short angry reaction clip from the Um Filho Irritante video used for fails and frustrating moments.
This is a very short burst of frustrated Portuguese from Brazilian creator Inutilismo, who snaps the phrase mas que merda with real irritation in his voice. The delivery is loud, fast and clipped, lasting under two seconds with no music or effects behind the shout. It lands like an instant outburst rather than a joke setup, which is why it works so well as a reaction. Viewers immediately read it as someone losing patience with something stupid, annoying or completely broken, and the abruptness makes the moment funnier.
