The exact original recording behind this clip is not widely documented, so it is best understood as internet slang rather than a line from a known film or show. Cállate is Spanish for shut up, while aweonao is a Chilean variation of weón, used among friends as a teasing insult for someone acting foolish. The phrase spread through Spanish-speaking meme pages, short videos and chat audios, where its blunt rhythm made it easy to reuse. It stays popular because it is short, instantly understood by Chilean and Latin American audiences, and works as a universal shut-down.
