It sounds like QAnon, but it actually describes a liberal conspiracy theory:
A loosely organized network of Democrat voters, politicians and media personalities who spread left-wing conspiracy theories such as the Russia Hoax, Jussie Smollett hoax, Ukraine hoax, Covington Kids hoax, and Bret Kavanaugh hoax. Blue Anon adherents fervently believe that right-wing extremists are going to storm Capitol Hill any day now and “remove” lawmakers from office, hence the need for the deployment of thousands of National Guard stationed at the US Capitol.
They should probably include Trump Derangement Syndrome on the list. Currently this definition is posted at Urban Dictionary, but it was taken down soon after it appeared and so it may disappear down the rabbit hole yet again.
