No byline, acknowledging that it's part of series that usually doesn't have them. Google trends has nothing for the phrase right now. UD, as of this writing, never heard of the expression (although don't be too surprised if someone swoops in to "correct" that later). Even for a generation that's ostensibly not going to have a huge social media footprint yet, that's rather remarkable for a supposed "biggest insult".
