Don Tacos is a Japanese tortilla chip snack, and its name is instantly recognised in Japan from television advertising where short sung slogans were used to make the product memorable. Clips of the jingle later circulated online outside Japan, where most listeners do not know the snack but enjoy the confident, cheerful delivery as a random meme sound. It has since been shared on soundboards as a standalone clip, reused in edits and reactions precisely because it sounds like a complete commercial interrupting whatever came before it.
