Reference Laundering

An article, poll, study, etc. which on face value would be dismissed, that is cited in progressively more reputable sources, until the original nonsense has credibility.

Person1: “I read on Politico that intero-recto-gestion is actually healthier then eating with your mouth.”
Person2: “That article is total Reference Laundering. If you click on the reference, Politico cited Vox, who cited Mashable, who cited Unicorn Riot, who cited an Onion Article based on a South Park episode.”
Person1: “so I’ve been shoving food up my butt for no reason!”
