The phrase is Spanish slang for saying something looks or tastes delicious, and the humour comes from stretching the last word far beyond its normal length. Short reaction clips like this travel on social video and messaging apps, where one expressive line can stand in for a comment. This one sits alongside other short reaction sounds like oh my god, wow, giving creators a way to signal delight without explaining it. Its brevity is part of its staying power, since it fits over a reveal, a bite or a glance and works across food, fashion and comedy edits.
