The phrase ai que delicia is everyday Portuguese in Brazil, used to say something tastes wonderful, and pairing it with Goku connects it to Dragon Ball, the long running anime where the hero is famous for eating enormous meals. Short Portuguese voice clips like this circulate widely in Brazilian group chats, edits and soundboards, where a familiar anime voice saying a very local expression creates the humour. Its brevity keeps it reusable far beyond food, as a mock dramatic approval of anything someone clearly enjoys.
