The clip circulates as part of a Portuguese palavrões collection credited to Tugas Doidos, built from funny moments the uploader recorded from the YouTube channel Kesyn and Skelter. Pai do Ruca became the recognisable voice behind this particular swear reaction, and the very short cut helped it spread on soundboards and in edited videos. In Portugal caralho is a common strong swear word used for shock, anger and comic emphasis, so the sound travels easily between gaming, football and everyday fail clips where one sharp word says everything.
