The clip comes from a Spanish language fandub animation based on Undertale, the 2015 role playing game created by Toby Fox, with Sans revoiced for comic effect. Fans cut single shouted lines like this one from longer fandub videos and turned them into shareable meme sounds. Its appeal is the contrast between Sans and the childish logic of calling the ocean soup because it is salty and full of things floating in it. Spanish speaking meme pages and soundboards kept the line circulating long after the original edit.
