I mean, personally I think people don't preserve the word order of the "little a salami" because it's awkwardly wrong. There are plenty of funny-word-order meme phrases that get preserved; that one gets inadvertently autocorrected by peoples' brains because it's high friction
also: it's getting lossily compressed, that's how you can tell the funny-word-order bit is just less important for most people than "as a treat" as a bit
