The clip comes from Portuguese meme sharing, where short spoken catchphrases are reused out of context as instant replies. Se você não gostou is a fragment that implies the rest of the attitude without needing a longer speech, which helps it travel across edits and chats. It has stayed in use because the meaning is clear even for viewers who catch only the tone, turning a simple if you did not like it into a reusable brush off for criticism, teasing and playful arguments online.
